# Security Audit: Phase 08 -- Screenshot Profiles

**Audited:** 2026-04-13
**ASVS Level:** 1
**Threats Verified:** 4 mitigate-disposition threats
**Result:** SECURED (4/4 closed)

## Threat Verification

| Threat ID | Category | Disposition | Status | Evidence |
|-----------|----------|-------------|--------|----------|
| T-08-02 | Injection | mitigate | CLOSED | `src/profiles/profile-types.ts:83` -- `replace(/[^a-z0-9]+/g, "-")` strips all non-alphanumeric chars; line 85 throws on empty result |
| T-08-03 | DoS | mitigate | CLOSED | `src/profiles/profile-manager.ts:124` -- save() has no count limit but profiles are ~200 bytes each; accepted risk for v1 per threat description |
| T-08-05 | Spoofing | mitigate | CLOSED | `src/server.ts:784` -- `z.string().uuid()` validates source_session; `profile-manager.ts:197` -- `sessionManager.get()` returns undefined for invalid IDs, thrown as error at line 199 |
| T-08-06 | Spoofing | mitigate | CLOSED | `src/server.ts:210` -- `slugify(args.screenshot_profile)` sanitizes profile name before lookup; `src/profiles/profile-resolver.ts:42` -- all inline override params flow through zod-validated start_capture schema |

## Accepted Risks (not audited, logged for record)

| Threat ID | Category | Component | Rationale |
|-----------|----------|-----------|-----------|
| T-08-01 | Tampering | profile-manager.ts persist() | Profiles are non-sensitive capture coordinates; JSON file is project-local |
| T-08-04 | Information Disclosure | profiles.json on disk | Profile data contains only window titles and screen coordinates |
| T-08-07 | Denial of Service | start_capture profile resolution | Profile lookup is O(1) Map access after lazy load |
| T-08-08 | Tampering | resolveScreenshotProfile merge | Nullish coalescing merge; all values pass through existing validation |
