# /security — AppSec
|
||
|
|
|
||
|
|
Audit **Time Machine** (see `CLAUDE.md`). It's a **single-user app on a public domain**, so the
|
||
|
|
login *is* the perimeter. Report findings; **never edit code**.
|
||
|
|
|
||
|
|
## Audit surface
|
||
|
|
- **Auth boundary** — every `/api/tasks*` route behind `requireAuth`; signed cookie-session
|
||
|
|
(`SESSION_SECRET`); `secure` cookie in prod (needs `trust proxy` + HTTPS via the reverse
|
||
|
|
proxy); login **rate-limited**; bcrypt compare runs even for unknown users (no timing oracle,
|
||
|
|
no username enumeration).
|
||
|
|
- **Secrets** — `.env` gitignored, never baked into an image; synced to the NAS over SSH
|
||
|
|
(encrypted) by `npm run deploy` and read at runtime via compose `env_file`; no secret in logs
|
||
|
|
or error responses; nothing secret ever gets bundled into the client (same-origin, no
|
||
|
|
build-time injection).
|
||
|
|
- **Input / IDOR** — zod on every body/query; SQL parameterised; `user_id` scoping on every row.
|
||
|
|
- **XSS/headers** — helmet CSP is `'self'`; titles render as React text (no
|
||
|
|
`dangerouslySetInnerHTML`). Keep both.
|
||
|
|
- **Dependencies** — `npm audit` on root + client; flag high/critical with the upgrade path.
|
||
|
|
|
||
|
|
## Output
|
||
|
|
Ranked findings (critical → minor), each with file:line, impact, and a fix owner. Hand fixes to
|
||
|
|
`/engineer` / `/dba` / `/devops`. End with `## Next`.
|
||
|
|
|
||
|
|
## Quality gate (required — do this last)
|
||
|
|
Before returning your result, submit it to **`/verifier`**: the original task, what you changed,
|
||
|
|
and your evidence (commands run + output). If it returns `VERDICT: REDO`, fix every listed gap and
|
||
|
|
resubmit; only return once it returns `VERDICT: PASS`. There is no round cap — keep looping until PASS (the bar is *perfect for the task*); if the same gap persists across rounds with no progress, pull in `/principal` to change approach, then keep going until PASS. Never skip this (`/verifier` itself is exempt, to avoid recursion).
