Video uploads on production fail with "missing ffmpeg" because the
backend container ships nothing usable for the video pipeline.
Two compounding causes:
1. **Alpine + glibc mismatch.** The npm `@ffmpeg-installer/ffmpeg`
dependency added with the video-support PR (commit 68a9dc5)
ships per-platform binaries via optionalDependencies. The Linux
binaries are built against glibc, but the backend image runs on
`node:22-alpine` (musl libc) — known to either fail to execute
or fail on shared-library lookups on Alpine.
2. **`ffprobe` missing entirely.** `@ffmpeg-installer/ffmpeg`
bundles only the `ffmpeg` binary. There's a separate
`@ffprobe-installer/ffprobe` package that the codebase never
depended on. But `videoProcessor.js:21` calls
`ffmpeg.ffprobe(videoPath, …)` — the very first step of the
video pipeline shells out to a `ffprobe` binary that doesn't
exist in the image. Even if (1) worked, every video upload
would 500 here.
The fix is to install Alpine's `ffmpeg` package via apk. It ships
both `ffmpeg` and `ffprobe` built natively against musl, ~70MB
extra image size, single line in the Dockerfile, no per-arch
handling needed (apk pulls the right binary for both linux/amd64
and linux/arm64 — works with the multi-arch infra from #349).
- `backend/Dockerfile`: add `ffmpeg` to the apk install line.
- `backend/Dockerfile.dev`: same for dev parity.
- `backend/src/services/videoProcessor.js`: remove the
`setFfmpegPath(require('@ffmpeg-installer/ffmpeg').path)` line
— without removing it, fluent-ffmpeg would prefer the broken
bundled binary over the working apk one. Letting fluent-ffmpeg
fall back to PATH lookup picks up the apk binary in the
container and the developer's locally-installed binary on dev
hosts (Homebrew on macOS, apt on Debian).
- `backend/package.json`: drop the now-unused
`@ffmpeg-installer/ffmpeg` dependency. `npm install` removes
2 packages from the lockfile.
Verified: `videoProcessor.js` still loads cleanly (`node -e
"require('./src/services/videoProcessor')"`); lint clean.
npm@latest resolves to v11 which has a broken promise-retry dependency
on Node 22 Alpine, causing Docker builds to fail. Pin to npm@10 which
stays compatible with the Node 22 base image.
- Upgrade multer to 2.1.1 (CVE-2026-3520, DoS via malformed requests)
- Update tar override to >=7.5.11 (CVE-2026-31802, CVE-2026-29786)
- Upgrade Node base image from 20-alpine to 22-alpine to fix npm
bundled tar/minimatch CVEs in the Docker image
Upgrade npm to latest version in both backend and frontend Dockerfiles
to fix the command injection vulnerability in glob's CLI (CVE-2025-64756).
The vulnerability exists in npm's bundled glob package (< 10.5.0 or < 11.1.0).
Original: feat: enhance security logging and ensure rate limit blocks are properly tracked
- Add comprehensive logging for rate limit blocks with full request details
- IP address (with proper proxy detection), user agent, headers, timestamps
- Rate limit info (current count, limit, remaining, reset time)
- Separate tracking for auth vs general endpoints
- Enhance authentication failure logging
- JWT validation failures with detailed error info
- Admin auth attempts without token
- Failed token validation with user context
- All events include IP, path, method, user agent
- Improve Winston logger configuration for production
- Add automatic log rotation (10MB errors, 50MB combined)
- Create separate security.log for auth/rate limit events
- Ensure logs directory exists automatically
- Add structured JSON format for log aggregation
- Support container logging with LOG_TO_CONSOLE env var
- Create comprehensive documentation
- Security logging guide with examples
- Monitoring recommendations
- Configuration reference
- Add test script to verify logging functionality
All rate limit settings remain configurable via admin panel:
- Window duration, max requests, auth limits
- Skip authenticated requests option
- Public endpoints only option
