Superset uses msgpack exclusively for SQL Lab asynchronous query result serialization (`RESULTS_BACKEND_USE_MSGPACK`); the Unpacker is never reused across error boundaries in production code paths. | +| **msgpack** | GHSA-j586-36cw-2gc2 | HIGH | `1.2.3` | `>=1.2.3` | Memory leak in the C extension when map key validation raises an exception during unpacking (triggers with default `strict_map_key=True` when a map key is not `str`/`bytes`). In Superset, msgpack deserialization via `msgpack.loads(payload, raw=False)` in `superset/views/utils.py` uses this default on cached query results from the results backend, whose provenance is internal Celery worker execution rather than direct user input. Operators should upgrade to `msgpack>=1.2.3` (Option A) to eliminate the leak path directly rather than relying on payload non-reachability. | +| **pyarrow** | CVE-2026-25087 | HIGH | `23.0.1` | `>=25.0.1` | Use-after-free in the Arrow C++ IPC file reader with pre-buffering (GHSA-rgxp-2hwp-jwgg). Superset invokes the Parquet reader for user data uploads and the IPC stream reader (`RecordBatchStreamReader`) for SQL Lab asynchronous query result serialization; it does not invoke the IPC file reader (`RecordBatchFileReader` with pre-buffering). Upstream fixes start at `23.0.1`, with `>=25.0.1` enforced as Superset target floor in this PR. | + +## 2. Dependency Constraint Architecture + +Apache Superset manages dependencies across two layers: + +1. **Package Declarations (`pyproject.toml` and `superset-core/pyproject.toml`)**: + Specifies flexible semantic version ranges to avoid dependency resolver conflicts in downstream custom deployments. + - `cryptography` (`pyproject.toml`): `>=50.0.2, <51.0.0` (enforces remediated releases covering PKCS#7, path-building, certificate verification name constraints, and wheel OpenSSL advisories). + - `msgpack` (`pyproject.toml`): `>=1.2.3, <1.3` (enforces remediated releases covering both GHSA-6v7p-g79w-8964, fixed in 1.2.1, and GHSA-j586-36cw-2gc2, fixed in 1.2.3). + - `pyarrow` (`pyproject.toml` and `superset-core/pyproject.toml`): `>=25.0.1, <26` (enforces modern non-vulnerable engines in both core and main packages). + +2. **Locked Requirements (`requirements/base.in` and `requirements/base.txt`)**: + Pins exact validated versions for official Docker images and deterministic continuous integration builds. + +## 3. Operator Mitigations & Container Workarounds + +If you are running an existing container image where dependency constraints prevent direct pip upgrades, the following approaches allow immediate remediation without breaking Superset: + +### Option A: Extend Official Docker Image with Patched Dependencies + +The official Docker image executes Superset inside a Python virtual environment located at `/app/.venv`. To ensure upgraded dependencies are installed directly into Superset runtime rather than the root container system packages, use `uv pip install --python /app/.venv/bin/python` (or `/app/.venv/bin/pip install` in environments without `uv`). + +When upgrading `cryptography>=50.0.2`, `pyOpenSSL` must also be upgraded to `>=26.4.0` (matching the version pinned in `requirements/base.txt`). pyOpenSSL releases prior to 26.4.0 cap `cryptography` below 50 (with 25.x releases also attempting to access `_lib.GEN_EMAIL` when `OpenSSL.crypto` is imported, which is no longer exposed in cryptography 50.x). Upgrading pyOpenSSL to `>=26.4.0` alongside cryptography satisfies the dependency resolver and ensures imports of `OpenSSL` (used by Snowflake private key authentication and Google Cloud mutual TLS) succeed without error: + +```dockerfile +FROM apache/superset:latest + +USER root +RUN uv pip install --no-cache-dir --python /app/.venv/bin/python \ + "cryptography>=50.0.2" \ + "pyopenssl>=26.4.0" \ + "msgpack>=1.2.3" \ + "pyarrow>=25.0.1" + +USER superset +``` + +### Option B: Scanner Triage and Ignore Rules (`.trivyignore`) + +For organizations maintaining automated compliance gates, findings where the specific vulnerable code path is not reachable in the shipped Superset version and configuration can be documented and suppressed in `.trivyignore`: + +```text +# CVE-2026-69247: PKCS#7 EnvelopedData decryption is not used by Superset +CVE-2026-69247 + +# CVE-2026-69249: Untrusted X.509 certificate path-building is not exposed in request processing +CVE-2026-69249 + +# CVE-2026-69248: Cryptography X.509 certificate verifier APIs (cryptography.x509.verification) are not called by Superset +CVE-2026-69248 + +# GHSA-537c-gmf6-5ccf: Wheel-bundled OpenSSL is not directly exposed; upgraded via Option A +GHSA-537c-gmf6-5ccf Review Comment: Addressed in commit 15aae17857d83f31b9a977ff69e14bfabe1da252. Updated the `.trivyignore` template in Option B to include both CVE and GHSA aliases for each multi-identifier advisory (wheel OpenSSL CVE-2026-34180 / GHSA-537c-gmf6-5ccf, msgpack Unpacker CVE-2026-57585 / GHSA-6v7p-g79w-8964, and pyarrow IPC file reader CVE-2026-25087 / GHSA-rgxp-2hwp-jwgg). Added an explicit note in the preamble explaining that Trivy requires suppression rules to match the exact identifier reported by the scan engine. -- This is an automated message from the Apache Git Service.
