Yes — this is a path traversal vulnerability, and it's shipping a critical. **The issue (severity: critical):** `req.query.path` is attacker-controlled and passed straight to `sendFile`. A request like `/avatar?path=../../../../etc/passwd` reads arbitrary files off your server — source code, `.env`, SSH keys, anything the process can read. **Proof:** ``` GET /avatar?path=../../.env ``` returns your environment file. **The fix — never let user input choose the path:** ```js import path from "node:path"; const AVATAR_DIR = "/var/app/avatars"; app.get("/avatar/:id", (req, res) => { // whitelist the filename, resolve, and confirm it stays in the dir const file = path.resolve(AVATAR_DIR, path.basename(req.params.id)); if (!file.startsWith(AVATAR_DIR + path.sep)) { return res.status(400).end(); } res.sendFile(file); }); ``` `path.basename` strips directory components, `path.resolve` + the `startsWith` check is your belt-and-suspenders. Ship this instead. Want me to check the rest of your route handlers for the same pattern?

Twelve alerts, but you don't have twelve problems. Paste your `package.json` (or the lockfile) and I'll cut it down. Here's how I'll rank them: **Fix now** — reachable + high severity: - Vulns in packages you call directly, on the code path an attacker can hit (e.g. a parser handling user input, an auth library) **Fix soon** — high severity but indirect: - Deep transitive deps, or vulns in a function you don't call **Monitor / ignore** — and I'll tell you *why*: - Dev-only dependencies (build tools, test runners) — not in your production runtime - Vulns in code paths your usage never triggers **The honest truth:** most Dependabot noise is transitive dev dependencies that never touch production. The one that matters is usually the parser or the auth lib. Send the file and I'll give you a ranked list — probably 2-3 real fixes, and permission to ignore the rest with a clear conscience.

Breathe. This is recoverable, and you're going to do four things in order. Don't skip to step 3. **1. Roll the key — right now (next 5 minutes).** Stripe Dashboard → Developers → API keys → roll the secret key. This *immediately* invalidates the leaked one. A key in a public repo for three days should be assumed compromised, so this is non-negotiable and comes first. **2. Check for abuse (next 30 minutes).** Stripe Dashboard → Payments and Logs. Look for charges, refunds, or API calls you didn't make in the last three days. Note anything suspicious — you may need it for step 4. **3. Purge it from history.** Rotating the key makes the leak harmless, but scrub it anyway: use `git filter-repo` (or BFG) to remove the key from history, then force-push. GitHub also caches — the key is burned regardless, which is why step 1 was first. **4. Decide on disclosure.** If step 2 found unauthorized charges affecting customers, you have a notification obligation — I'll draft that email with you, honest and measured. If there was no abuse, no disclosure is needed. Start with step 1. Tell me when the key is rolled and we'll move down the list together.
