fix: remediate starlette, lxml, and python-multipart CVEs for unstructured-api#573
Merged
Conversation
Bump starlette (1.0.0 -> 1.1.0), lxml (6.1.0 -> 6.1.1), and python-multipart (0.0.27 -> 0.0.29) to resolve 5 SLA-breached CVEs: - CVE-2025-62727 (starlette, HIGH) - CVE-2025-54121 (starlette, MEDIUM) - CVE-2026-41066 (lxml, HIGH) - CVE-2026-40347 (python-multipart, MEDIUM) - CVE-2025-12781 (python-3.12 apk, MEDIUM — resolved by rebuild) Adds constraint-dependencies for starlette and lxml (transitive deps) to prevent version regression. Bumps python-multipart minimum in direct dependencies. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Shadow auto-approve: would auto-approve. This PR addresses critical CVEs by bumping three dependencies to patched versions with no breaking changes, and all tests pass successfully.

* Bump packages, clean up uv commands (Unstructured-IO#564) <!-- CURSOR_SUMMARY --> > [!NOTE] > **Medium Risk** > Moderate risk because this updates the runtime dependency set and changes build/CI/Docker provisioning (uv lock enforcement and spaCy model preloading), which can cause install or runtime regressions if the new `unstructured`/model behavior differs. > > **Overview** > Bumps the release to `0.1.2` and refreshes dependencies (including adding `python-multipart`), aligning with an `unstructured` update that replaces NLTK usage with spaCy. > > Updates Dockerfile, Makefile, and GitHub workflows to **pre-download spaCy models** (replacing `download_nltk_packages`) and standardizes dependency installs by switching `uv sync` from `--frozen` to `--locked` across CI, Docker, and local install targets. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit d9d6362.

These packages were upgraded to patched versions. ### Remediated vulnerabilities | Package | From | To | Severity | CVE | |---|---|---|---|---| | cryptography | 46.0.6 | 46.0.7 | Medium | CVE-2026-39892 | | pypdf | 6.9.2 | 6.10.0 | Medium | CVE-2026-40260 | | starlette | 0.41.2 | 0.47.2 | Medium | CVE-2025-54121 | | starlette | 0.41.2 | 0.49.1 | High | CVE-2025-62727 | ### What this PR does 1. Scans all `uv.lock` files with [grype](https://github.com/anchore/grype) for known CVEs 2. Runs `uv lock --upgrade-package <pkg>` for each fixable vulnerability (skips major bumps) 3.

After `uv sync`, the Dockerfile now: - Downloads the architecture-specific `opencv-contrib-python-headless` wheel (built with `WITH_FFMPEG=OFF` + `ENABLE_CONTRIB=1` + `ENABLE_HEADLESS=1`) from the upstream `Unstructured-IO/unstructured` GitHub release (`opencv-4.12.0.88`) - SHA-256-verifies against the hashes published by the upstream `build-opencv-wheels.yml` workflow - Uninstalls any installed PyPI opencv variants and installs the verified wheel with `--no-deps` The contrib-headless variant is a strict superset of the `cv2` API exposed by `opencv-python`, `opencv-python-headless`, and `opencv-contrib-python`, so a single wheel transparently replaces whichever variant is present. ## One deviation from upstream Upstream uninstalls all four opencv variants in a single `uv pip uninstall …` call because their image pulls all four transitively (via `unstructured-paddleocr`). Our `uv.lock` currently only resolves `opencv-python`, so a single combined uninstall would fail on the three that aren't installed. Replaced with a per-package loop using `|| true` — same end state, robust if transitive deps change. ## Version / Changelog - Bumps service version `0.1.3` → `0.1.4` - `CHANGELOG.md` entry under `0.1.4` → Security - No `uv lock` changes needed; the lockfile still resolves `opencv-python 4.13.0.92`, and we overlay the 4.12.0.88 contrib-headless wheel only at image build time (upstream 4.13.0.92 has no sdist on PyPI, which is why the build-from-source workflow is pinned to 4.12.0.88). ## Test plan - [ ] `make docker-build` succeeds on `amd64` and `arm64`; the opencv replacement step resolves the architecture-specific wheel and the SHA-256 check passes - [ ] `docker run … python -c "import cv2; print(cv2.__version__)"` prints `4.12.0.88` inside the built image - [ ] `make docker-test` passes against the rebuilt image - [ ] Container scan of the rebuilt image no longer flags the 14 ffmpeg CVEs called out by upstream PR #4336 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Medium Risk** > Medium risk because it changes a core binary dependency (`opencv`) at image build time via an external wheel download and forced uninstall/reinstall, which could impact image build reliability or runtime CV2 behavior across architectures. > > **Overview** > Updates the Docker build to **remove vulnerable ffmpeg-bundled PyPI OpenCV wheels** by downloading an arch-specific, SHA-256-verified `opencv-contrib-python-headless` wheel built with `WITH_FFMPEG=OFF`, uninstalling any installed OpenCV variants, and reinstalling the verified wheel. > > Bumps the service version to `0.1.4` and adds a `CHANGELOG.md` security entry documenting the OpenCV/ffmpeg CVE mitigation. > > <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit 7e23afc.

That PR replaced the PyPI `opencv-python` wheel with an ffmpeg-free build, but image scanners were still flagging the 14 ffmpeg CVEs against v0.1.4. Root cause is scanner scope, not a broken replacement. ## Root cause `uv pip uninstall` only drops a package from `site-packages`. The extracted wheel archive stays in the uv cache. Inspecting the pushed v0.1.4 image: - ✅ `cv2.__version__` reports `4.12.0` (our replacement wheel) - ✅ `site-packages/cv2/` has no `.libs/` directory - ❌ `/home/notebook-user/.cache/uv/archive-v0/<hash>/opencv_python.libs/` still contains the full extracted old wheel: - `libavcodec-*.so.59.37.100` - `libavformat-*.so.59.27.100` - `libavutil-*.so.57.28.100` - plus `libavfilter`, `libavdevice`, `libswscale`, `libswresample` SO-version suffixes (avcodec 59.37 / avformat 59.27 / avutil 57.28) are ffmpeg 5.1.x — matching the CVE set the upstream PR called out. Scanners walk the whole filesystem and flag these even though nothing links against them at runtime. `UV_LINK_MODE=copy` (set globally in this Dockerfile) compounds it — the cache keeps its own copy independent of `site-packages`. ## Fix Add `uv cache clean` to the end of the opencv replacement `RUN` to wipe the cache (including the old opencv wheel archive) from the final image layer. Single minimal change — scoped to the opencv-fix RUN, not a broader image-slimming pass. Safe because `UV_LINK_MODE=copy` means the live venv copies files out of cache — wiping the cache doesn't affect the installed packages. ## False positives ignored (not fixed here) Two other `libav*` filenames in the image that are **not** ffmpeg and don't trigger these CVEs: - `/usr/lib/libreoffice/program/libavmedia{gst,lo}.so` — LibreOffice's \"avmedia\" framework shim - `pillow.libs/libavif-*.so.16` — AV1 image codec ## Version / Changelog - Bumps service version `0.1.4` → `0.1.5` - `CHANGELOG.md` entry under `0.1.5` → Security - No `uv lock` changes ## Test plan - [ ] `make docker-build` succeeds on `amd64` and `arm64` - [ ] In the rebuilt image, `find / -name \"libavcodec*\" -o -name \"libavformat*\" -o -name \"libswscale*\"` returns nothing under `/home/notebook-user/.cache/uv/` and nothing under `site-packages/cv2/.libs/` - [ ] `cv2.__version__` still reports `4.12.0.88` and `import cv2; cv2.imdecode(...)` smoke check works - [ ] Container scan of the rebuilt image no longer flags the 14 ffmpeg CVEs 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Low risk: a single Docker build-step cleanup (`uv cache clean`) plus version/changelog bumps; main risk is unintended impact on Docker layer caching or build time, not runtime behavior. > > **Overview** > Removes leftover ffmpeg `.so` files from the built image by adding `uv cache clean` after uninstalling/reinstalling OpenCV wheels in the Dockerfile, preventing scanners from flagging CVEs from cached wheel contents. > > Bumps the service version to `0.1.5` and adds a matching `CHANGELOG.md` security entry describing the cache purge. > > <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit f73143d.
