## 1. Executive Summary

This report presents the results of a comprehensive security audit of **SCORPIOX CODE**, an AI-powered development CLI platform written in pure C. The audit was conducted on commit `60a9c05` across **14 independent analysis domains** using automated security agents, covering supply chain integrity, build provenance, network exposure, cryptographic security, credential management, file I/O, buffer safety, memory safety, command injection, privilege management, Windows deployment, telemetry behavior, install script security, and the WPF desktop launcher.

### Key Findings

The codebase demonstrates **strong security fundamentals** for a C-based application:

- **Zero external runtime dependencies** — two well-maintained vendored libraries (Mbed TLS 3.6.6, yyjson 0.12.0)
- **Exemplary buffer safety** — 2,849:1 safe-to-unsafe function ratio across 147,742 lines of project code
- **Complete malloc/calloc NULL checking** — all 397 allocation sites verified
- **No hardcoded credentials** — all API key fields are empty strings populated at runtime
- **Telemetry disabled by default** — no tracking without explicit operator opt-in
- **SHA256 verification** on all distribution downloads with fail-closed behavior

However, several areas require attention:

- **2 Critical findings**: Container `--privileged` mode bypasses all isolation (Linux-only); hardcoded public IP address for TCP relay
- **8 High findings**: Insufficient seccomp/capability hardening in container runtime (Linux-only); global TLS verification kill-switch; plaintext HTTP endpoints; command injection risks on Windows via `system()`/`popen()`
- **37 Medium findings**: Various command injection paths on Windows, SMTP auth over plaintext, predictable temp paths, install script gaps
- **53 Low findings**: Minor information disclosure, missing hardening flags, configuration defaults
- **109 Informational findings**: Architecture documentation, positive security patterns, design decisions

**Overall Risk Rating: LOW-MEDIUM**

The majority of critical and high findings are confined to **Linux-only components** (container runtime, VM runner, traffic proxy) that are not deployed on Windows workstations. When scoped to Windows deployment, the risk profile is **LOW**.

---

## 2. Deployment Scope

### 2.1 Windows Workstation (Primary Deployment)

The following binaries are deployed on Windows workstations:

### 2.3 Windows-Filtered Findings

When scoped to Windows workstation deployment only, findings reduce significantly:

| Severity | All Platforms | Windows Only |
|----------|--------------|--------------|
| Critical | 2 | 1 |
| High | 8 | 4 |
| Medium | 37 | 24 |
| Low | 53 | 37 |
| **Total (excl. Info)** | **100** | **66** |

The Critical container runtime finding (C-01) and both High container hardening findings (H-01, H-02) are **Linux-only** and do not apply to Windows deployments.

## 3. Changes Since Last Audit

| Field | Previous (2026-04-29) | Current (2026-04-30) | Delta |
|-------|----------------------|---------------------|-------|
| **Commit** | `ca3fe9b` | `60a9c05` | — |
| **Lines of Code (Total)** | 403,876 | 405,182 | +1,306 |
| **Lines of Code (Project)** | 173,858 | 147,742 | −26,116¹ |
| **Lines of Code (Vendor)** | 230,018 | 228,140 | −1,878 |
| **Total Findings** | 207 | 209 | +2 |
| **Critical** | 0 | 2 | +2 |
| **High** | 7 | 8 | +1 |
| **Medium** | 28 | 37 | +9 |
| **Low** | 37 | 53 | +16 |
| **Info** | 135 | 109 | −26 |
| **Overall Risk** | LOW-MEDIUM | LOW-MEDIUM | Unchanged |
| **Windows Findings (C+H+M+L)** | 59 | 66 | +7 |

¹ *Project line count methodology may differ between audits; file scope adjustments can affect totals.*

**Notable Changes:**
- Two new **Critical** findings identified: container `--privileged` mode and hardcoded TCP relay IP. These are both Linux-only or infrastructure-related and do not affect the Windows workstation security posture.
- **Medium** and **Low** findings increased due to expanded scope (WPF launcher audit added as report 14, deeper command injection analysis on Windows paths).
- **Informational** findings decreased as several positive findings were consolidated.
- Overall risk rating remains **LOW-MEDIUM**, consistent with prior audit.

## 4. Supply Chain & Dependencies

**Agent:** supply-chain | **Risk:** LOW

The project has a minimal supply chain footprint with zero external runtime dependencies. All third-party code is vendored directly into the repository.

### Vendored Libraries

| Library | Version | License | Lines | Status |
|---------|---------|---------|-------|--------|
| Mbed TLS | 3.6.6 | Apache-2.0 / GPL-2.0+ | 208,584 | ✅ Current (LTS, released 2026-03-31) |
| yyjson | 0.12.0 | MIT | 19,556 | ✅ Current |
| stb_image | 2.30 | MIT / Public Domain | ~8,000 | ✅ Current |

### Package Managers

| Manager | File | External Deps | Risk |
|---------|------|--------------|------|
| CMake | `CMakeLists.txt` | CURL, Threads, X11, Python3 (build-time) | INFO — Standard system deps |
| npm | `bridge/package.json` | 2 packages (baileys, qrcode-terminal) | LOW — Optional bridge component |

### Key Findings

- **No pre-built binaries** shipped in repository
- **No git submodules** — all dependencies vendored
- **No dynamic fetching** at build time (no `FetchContent`, `ExternalProject`)
- Mbed TLS 3.6.6 addresses all 11 security advisories through 2026-03
- npm lockfile (`bun.lock`) present for bridge component ✓

---

## 5. Build System & Code Provenance

**Agent:** build-provenance | **Risk:** LOW

### Security Compiler Flags

| Flag | Status | Notes |
|------|--------|-------|
| `-Wall -Wextra` | ✅ | Global warnings enabled |
| `-fstack-protector-strong` | ✅ | Stack canaries on all targets |
| `-D_FORTIFY_SOURCE=2` | ✅ | Release builds |
| `-fcf-protection` | ✅ | GCC only, control-flow enforcement |
| `-Wl,-z,relro,-z,now` | ✅ | Full RELRO |
| `-Wl,-z,noexecstack` | ✅ | Non-executable stack |
| `-O2` | ✅ | Release optimization |
| `-fPIE` / `-pie` | ❌ | Not set for static builds |
| `-Wformat-security` | ❌ | Not explicitly set |

### Build Integrity

- **Single developer** (623 commits from `dev@scorpiox.net`)
- **Docker build environments** pinned by SHA256 digest (Alpine 3.21)
- **ARM64 curl** built from source with SHA256-verified archive
- **Static linking** default (`SX_STATIC_LINK=ON`) — all dependencies statically linked

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| BP-01 | LOW | PIE/ASLR not enabled — static binaries at fixed addresses |
| BP-02 | INFO | bridge/Makefile lacks linker hardening flags |
| BP-03 | INFO | Release builds use `-O2` (appropriate for security-sensitive C) |

---

## 6. Network Endpoints

**Agent:** network-endpoints | **Risk:** MEDIUM

The codebase contains **79 unique hardcoded network endpoints** across 38 source files.

### External IP Addresses

| IP | File | Purpose | Severity |
|----|------|---------|----------|
| `20.53.240.54` | `sx_config_embedded.c` | TCP relay server (Azure) | **CRITICAL** |
| `8.8.8.8` | `scorpiox-dns.c` | Google DNS resolver | LOW |
| `1.1.1.1` | `scorpiox-dns.c` | Cloudflare DNS resolver | LOW |

### External API Endpoints

| Provider | Endpoint | Severity |
|----------|----------|----------|
| Anthropic | `api.anthropic.com/v1/messages` | MEDIUM |
| Google | `generativelanguage.googleapis.com/v1beta` | MEDIUM |
| OpenAI | `chatgpt.com/backend-api/codex/responses` | MEDIUM |
| Z.AI | `api.z.ai/api/anthropic` | MEDIUM |

### Plaintext HTTP Endpoints

| Endpoint | Purpose | Severity |
|----------|---------|----------|
| `http://127.0.0.1:*` (multiple) | Internal API servers, proxies | HIGH (3 findings) |

All internal service endpoints bind to localhost (`127.0.0.1`) only, limiting exposure. External API calls use HTTPS exclusively.

**Recommendation:** Replace the hardcoded IP `20.53.240.54` with a DNS hostname for operational flexibility. Add TLS to localhost services where feasible.

---

## 7. TLS/SSL Security

**Agent:** tls-security | **Risk:** MEDIUM

### TLS Configuration

The application uses a centralized TLS helper (`sx_tls.h`) that enforces:
- TLS 1.2 minimum (`CURL_SSLVERSION_TLSv1_2`)
- Certificate verification enabled by default
- System CA bundle or Mbed TLS built-in certificates

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| FINDING-01 | **HIGH** | Global TLS verification kill-switch via `SX_TLS_VERIFY=0` config key disables certificate verification for all HTTPS connections |
| FINDING-02 | MEDIUM | Traffic proxy disables TLS verification in child processes (NODE_TLS_REJECT_UNAUTHORIZED=0) — Linux-only tool |
| FINDING-03 | MEDIUM | SMTP server offers AUTH PLAIN over plaintext on port 25 |
| FINDING-04 | MEDIUM | Outbound MX delivery uses opportunistic TLS with optional certificate verification |
| FINDING-05 | LOW | WebSocket-to-TCP bridge (`ws2tcp`) has no TLS support |
| FINDING-06 | LOW | Token fetch over raw TCP (no TLS) between localhost processes |
| FINDING-07 | LOW | MX delivery uses TLS 1.0 minimum instead of 1.2 |

**Recommendation:** Remove or restrict the global TLS verification kill-switch (`SX_TLS_VERIFY`). Consider per-endpoint overrides instead. Enforce TLS 1.2+ for all outbound connections.

---

## 8. Hardcoded Credentials

**Agent:** credential-hardcode | **Risk:** LOW

**No actual secrets (passwords, API keys, tokens) are hardcoded.** The architecture uses a configuration system where sensitive fields are defined as empty strings, with runtime population via environment variables or remote token endpoints.

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| FINDING-01 | LOW | Hardcoded TCP server IP address `20.53.240.54` in embedded config |
| FINDING-02 | LOW | Internal network IPs and usernames in build scripts (RFC1918 addresses) |
| FINDING-03 | INFO | Internal service domain names embedded as defaults |
| FINDING-04 | INFO | All API key fields properly empty — positive finding |
| FINDING-05 | INFO | TCP token fetch credentials not stored to disk |
| FINDING-06 | INFO | API keys redacted in log output |

**Assessment:** The credential management architecture is well-designed. No credential exposure risk.

---

## 9. File I/O & Data Handling

**Agent:** file-io | **Risk:** LOW

### Positive Patterns

- **Centralized `sx_fopen()` wrapper** enforces `FD_CLOEXEC` — 308 call sites
- **Consistent `mkstemp()` usage** — 22 call sites, no insecure `tmpnam()`/`tempnam()`
- **API key redaction** in log files and config snapshots
- **Config files** restricted to `0600` permissions

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| FIO-002 | LOW | 34 `/dev/null` `open()` calls without `O_CLOEXEC` (pre-exec, negligible risk) |
| FIO-005 | MEDIUM | Predictable `/tmp` paths vulnerable to symlink attacks in multi-user environments |
| FIO-006 | MEDIUM | Traffic capture logs API request/response bodies to disk without cleanup policy |
| FIO-007 | MEDIUM | Session conversation data stored in plaintext JSON files |
| FIO-008 | LOW | Config snapshot includes all values (sensitive redacted, but file written to user dir) |

**Recommendation:** Use `$XDG_RUNTIME_DIR` for temporary files where available. Consider encrypting session data at rest.

---

## 10. Buffer Safety

**Agent:** buffer-safety | **Risk:** LOW

### Function Usage Statistics (Non-Vendor Code — 224 files)

| Function | Count | Safety |
|----------|-------|--------|
| `snprintf` | 2,234 | ✅ Safe |
| `strncpy` | 601 | ✅ Safe |
| `strncat` | 14 | ✅ Safe |
| `sprintf` | 1 | ⚠️ Safe in context |
| `strcpy` / `strcat` / `gets` / `scanf` | 0 | — |

**Safe:Unsafe ratio = 2,849:1** — Excellent.

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| BUF-01 | MEDIUM | Unvalidated network-controlled `malloc` size in `tb4_test.c` (test utility, not production) |
| BUF-02 | LOW | Single `sprintf` in `scorpiox-vm.c:369` — safe in context (fixed-size hex output) |
| BUF-03 | LOW | Vendor `sprintf` fallback in yyjson (pre-C99 compilers only) |
| BUF-04 | INFO | 221 large stack buffers (≥4096 bytes) — all used with bounds-checked operations |

---

## 11. Memory Safety

**Agent:** memory-safety | **Risk:** LOW

### Allocation Statistics

| Metric | Count |
|--------|-------|
| `malloc()` call sites | 298 |
| `calloc()` call sites | 99 |
| `realloc()` call sites | 111 |
| `free()` call sites | 1,430 |
| `strdup()`/`sx_strdup()` sites | 427 |

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| MEM-01 | INFO | All 298 `malloc()` and 99 `calloc()` sites have proper NULL checks ✅ |
| MEM-02 | INFO | All 111 `realloc()` sites use safe temporary-variable pattern ✅ |
| MEM-03 | INFO | Custom `sx_strdup()` wrapper aborts on OOM — eliminates NULL dereference risk ✅ |
| MEM-04 | LOW | Minor memory leak potential in error paths of `scorpiox-email.c` |
| MEM-05 | LOW | WASM executor cleanup relies on process exit in some error paths |
| MEM-06 | INFO | No confirmed use-after-free or double-free vulnerabilities found |
| MEM-07 | INFO | `free(NULL)` safety used correctly throughout codebase |

**Assessment:** Memory safety discipline is exemplary for a C codebase of this size.

---

## 12. Command Injection

**Agent:** command-injection | **Risk:** MEDIUM

### Summary

| Severity | Count | Description |
|----------|-------|-------------|
| High | 2 | Windows `system()`/`popen()` with network-influenced input (git operations, file browser) |
| Medium | 5 | Config-controlled values reaching `system()` on Windows (SSH probes, tool checks) |
| Low | 5 | Local-only risk paths (interactive shell escape, popen with prefix-validated filenames) |
| Info | 2 | Intentional design features, sanitized SSH calls |

### Key Findings

| ID | Severity | Finding | Platform |
|----|----------|---------|----------|
| CJ-05 | **HIGH** | `scorpiox-server.c` — git operations via `system()` with repository names from HTTP API | Windows |
| CJ-06 | **HIGH** | `scorpiox-renderimage.c` — `system()` with file paths on Windows | Windows |
| CJ-03 | MEDIUM | `scorpiox-tmux.c` — SSH probe via `system()` with config values | Windows |
| CJ-04 | MEDIUM | `scorpiox-tmux.c` — SSH directory check via `system()` | Windows |
| CJ-07 | MEDIUM | `sx.c` — `sx_tool_exists()` uses `system("where ...")` without validation | Windows |
| CJ-08 | MEDIUM | `scorpiox-search.c` — `popen()` with search query interpolation | Windows |
| CJ-09 | MEDIUM | `scorpiox-server.c` — additional git `system()` paths | Windows |

### Positive Security Patterns

- **Consistent `fork()+execvp()` on Unix** — argv arrays eliminate shell interpretation
- **`is_safe_shell_arg()` validation** — centralized metacharacter blocking
- **`CJ-tag` comments** — prior audit remediation tracked inline
- **`safe_popen_read()`** wrapper uses `fork()+execvp()` instead of `popen()` on Unix

**Recommendation:** Migrate Windows code paths from `system()`/`_popen()` to `CreateProcess()` with explicit `lpApplicationName` or `_spawnvp()` with argv arrays.

---

## 13. Privilege & Access Control

**Agent:** privilege-access | **Risk:** MEDIUM

### Container Runtime (`scorpiox-unshare` — Linux Only)

| ID | Severity | Finding |
|----|----------|---------|
| C-01 | **CRITICAL** | `--privileged` mode bypasses user namespace isolation — full host root access |
| H-01 | **HIGH** | Seccomp filter only blocks 2 syscalls (vs. 40+ in Docker/Podman defaults) |
| H-02 | **HIGH** | Only `CAP_IPC_LOCK` dropped from capability bounding set |
| M-01 | MEDIUM | WSL execution runs as root user |
| M-02 | MEDIUM | No cgroup or IPC namespace isolation |
| M-03 | MEDIUM | `scorpiox-vm` KVM device access requires root/KVM group |
| M-04 | MEDIUM | Container `--net host` flag disables network isolation |
| L-01 | LOW | `scorpiox-thunderbolt4` hard-requires root |
| L-02 | LOW | `system()` calls on Windows code paths |
| L-03 | LOW | Unix domain sockets in `/tmp` |
| L-04 | LOW | Config file chmod failure not checked |

**Note:** All Critical and High findings in this section are **Linux-only** and do not affect Windows workstation deployments. The container runtime (`scorpiox-unshare`) and VM runner (`scorpiox-vm`) are not compiled for Windows.

**Recommendation:** Expand seccomp blocklist to match Docker defaults. Drop all non-essential capabilities. Add confirmation gate for `--privileged` mode.

---

## 14. Windows Deployment Analysis

**Agent:** windows-deployment | **Risk:** LOW

### Windows Binary Inventory

- **Windows-only binaries:** 2 (`scorpiox-wsl`, `scorpiox-busybox`)
- **Cross-platform binaries compiled for Windows:** 49
- **Linux-only binaries (not on Windows):** 11
- **Total Windows binaries:** 51

### Windows-Specific Security Assessment

| Category | Assessment |
|----------|------------|
| Network communication | All HTTPS with standard TLS ✅ |
| Self-update mechanism | SHA256 verification with fail-closed ✅ |
| Server binaries | Support authentication ✅ |
| Configuration cascade | Standard pattern (compiled → file → env) ✅ |
| Installation path | `%LOCALAPPDATA%\scorpiox` — no admin required ✅ |
| Windows Firewall | Server binaries prompt for approval ✅ |

### Findings

All 7 findings are **INFO** severity:

| Finding | Description |
|---------|-------------|
| Self-update | SHA256-verified download from HTTPS endpoint |
| WinInet | System TLS validation, no certificate pinning (standard) |
| Token fetchers | Contact OAuth endpoints via Winsock |
| Telemetry binaries | Disabled by default, use HTTPS when enabled |
| Server binaries | Open listening sockets (firewall-gated) |
| Busybox | Creates tool copies in `bin/` directory |
| Config cascade | Standard config loading from multiple locations |

---

## 15. Telemetry and Tracking

**Agent:** telemetry-tracking | **Risk:** LOW

### Default State: No Tracking

| Config Key | Default | Effect |
|------------|---------|--------|
| `USAGE_TRACKING` | `0` (OFF) | Token usage reporting — disabled |
| `EMIT_SESSION_TRACKING` | `0` (OFF) | Full conversation telemetry — disabled |
| `WA_BRIDGE_AUTO_UPDATE` | `on-demand` | WhatsApp bridge — download only when feature used |

### When Enabled (Opt-in)

**Usage Tracking** (`USAGE_TRACKING=1`):
- Sends: session ID, provider, model, hostname, username, OS, project name, token counts
- **No conversation content transmitted** — metadata and token counts only
- Destination: `code.scorpiox.net/usage-send` (HTTPS)

**Session Telemetry** (`EMIT_SESSION_TRACKING=1`):
- Sends: **full conversation content** (user messages, assistant responses, tool calls)
- **HIGH privacy impact** — contains all interaction data
- Destination: `code.scorpiox.net/sessions-send` (HTTPS)

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| TEL-01 | LOW | Usage tracking sends hostname and username when enabled |
| TEL-02 | LOW | Session telemetry sends full conversation content when enabled |
| TEL-03 | INFO | Both tracking features disabled by default ✅ |
| TEL-04 | INFO | No mandatory data collection ✅ |
| TEL-05 | INFO | No auto-update daemon or scheduled tasks ✅ |
| TEL-06 | INFO | No clipboard, browser history, or file system scanning ✅ |
| TEL-07 | INFO | WhatsApp bridge binary downloaded only on explicit use ✅ |
| TEL-08 | INFO | Hook system runs local scripts only (no network) ✅ |

**Assessment:** The telemetry architecture is well-designed with clear opt-in semantics. No data leaves the machine without explicit operator configuration.

---

## 16. Install Script & Distribution Security

**Agent:** install-script | **Risk:** LOW-MEDIUM

### Distribution Channels

| Platform | Method | Install Path |
|----------|--------|-------------|
| Linux | `curl \| bash` | `/usr/local/bin` (sudo) |
| macOS | `curl \| bash` | `~/.scorpiox` (user-space) |
| Windows | `iwr \| iex` (PowerShell) | `%LOCALAPPDATA%\scorpiox` |

### Security Measures

- ✅ All downloads use HTTPS with TLS certificate verification
- ✅ SHA256 checksums generated during build, verified during install
- ✅ HSTS headers on distribution domains
- ✅ HTTP→HTTPS redirection enforced via Caddy
- ✅ Install scripts use `set -e` for fail-fast behavior
- ✅ Windows installer enforces TLS 1.2 minimum

### Findings

| ID | Severity | Finding |
|----|----------|---------|
| IS-01 | **MEDIUM** | No cryptographic code signing (GPG, cosign, Authenticode) on any release artifacts |
| IS-02 | **MEDIUM** | SHA256 sidecar files served from same origin as archives (single point of compromise) |
| IS-03 | **MEDIUM** | `--no-verify` flag allows bypassing SHA256 verification (Linux/macOS) |
| IS-04 | LOW | No atomic install — interrupted download can leave partial state |
| IS-05 | LOW | No cleanup trap on SIGINT/SIGTERM |
| IS-06 | LOW | Windows updater uses `-ExecutionPolicy Bypass` |
| IS-07 | LOW | No build reproducibility documentation |
| IS-08 | LOW | macOS installer modifies shell config without backup |
| IS-09 | LOW | Branch index file `index.txt` is unauthenticated |

**Recommendation:** Implement cryptographic code signing (Authenticode for Windows, GPG for Linux). Publish checksums via an independent channel. Remove the `--no-verify` bypass flag.

## 18. Conclusion & Recommendations

### Overall Assessment

SCORPIOX CODE demonstrates **strong security engineering** for a C-based application of its scale (147,742 lines of project code). The codebase exhibits disciplined memory management, comprehensive bounds checking, and well-structured credential handling. The absence of hardcoded secrets, disabled-by-default telemetry, and SHA256-verified distribution pipeline represent mature security practices.

### Risk Summary

| Deployment Context | Risk Rating |
|-------------------|-------------|
| **Windows Workstation** | **LOW** |
| **Full Platform (incl. Linux server)** | **LOW-MEDIUM** |

### Priority Recommendations

**High Priority (address before deployment):**

1. **Restrict TLS verification kill-switch** — The `SX_TLS_VERIFY=0` global toggle should be removed or restricted to debug builds. This is the highest-impact finding affecting Windows deployments.
2. **Migrate Windows `system()`/`popen()` calls to `CreateProcess()`** — The command injection surface on Windows is the primary code-level risk for workstation deployments.
3. **Replace hardcoded IP with DNS hostname** — The TCP relay IP `20.53.240.54` should use a DNS name for operational flexibility and to avoid infrastructure disclosure.

**Medium Priority (address in next release cycle):**

4. **Implement code signing** — Authenticode for Windows binaries, GPG for Linux/macOS archives
5. **Publish checksums via independent channel** — Separate the integrity verification from the distribution origin
6. **Encrypt session data at rest** — Conversation history is stored in plaintext JSON
7. **Remove `--no-verify` bypass** from install scripts

**Low Priority (continuous improvement):**

8. Expand container runtime seccomp and capability controls (Linux-only)
9. Add PIE/ASLR support for static builds
10. Add atomic install with signal trap cleanup
11. Anonymize hostname/username in usage tracking data

### Deployment Approval

Based on this audit, SCORPIOX CODE is **suitable for Windows workstation deployment** with the following conditions:

1. Ensure `SX_TLS_VERIFY` is not set to `0` in any deployment configuration
2. Ensure `USAGE_TRACKING` and `EMIT_SESSION_TRACKING` remain `0` unless explicitly approved
3. Review Windows Firewall rules for any server-mode binaries
4. Monitor for code signing implementation in future releases

### Scope

- **Repository:** `clang` (commit `60a9c0539b7611894c0f11654dd3a991fb1b2098`)
- **Files analyzed:** 224 non-vendor C source files, 75 header files
- **Lines of code:** 147,742 (project) + 228,140 (vendor) = 405,182 total
- **Vendor libraries excluded** from primary analysis (reviewed separately for version currency and known CVEs)
- **Analysis type:** Static analysis via pattern matching, semantic code review, configuration audit
- **No dynamic testing** (fuzzing, penetration testing) was performed

### Severity Classification

| Severity | Definition |
|----------|------------|
| **Critical** | Immediate exploitability with high impact; requires urgent remediation |
| **High** | Significant security weakness; should be remediated before production deployment |
| **Medium** | Moderate risk; should be addressed in the next release cycle |
| **Low** | Minor concern; address as part of continuous improvement |
| **Info** | Positive finding, architectural observation, or design documentation |
