########## docs/admin_docs/security/dependency-vulnerability-remediation.mdx: ########## @@ -0,0 +1,86 @@ +--- +title: Dependency Vulnerability Remediation & Scanner Guidance +sidebar_position: 3 +--- + +# Dependency Vulnerability Remediation & Container Scanner Guidance + +This guide addresses third-party dependency vulnerabilities reported by container security scanners (such as Trivy, Grype, and Snyk) in Apache Superset environments, specifically regarding dependency constraint handling for cryptography, msgpack, and pyarrow (referencing issue #45087). + +## 1. Vulnerability Applicability & Risk Assessment + +When security scanners evaluate Apache Superset container images, findings frequently arise in transitive or pinned direct dependencies. The table below details the applicability and actual exploitability surface of recently reported findings: + +| Package | Finding ID | Severity | Remediation Floor | Superset Code Path & Exploitability Analysis | +| :--- | :--- | :--- | :--- | :--- | +| **cryptography** | CVE-2026-69247 | HIGH | `>=50.0.0` | PKCS#7 EnvelopedData decryption denial of service. Superset does not consume, parse, or decrypt PKCS#7 or S/MIME enveloped data. | +| **cryptography** | CVE-2026-69249 | MEDIUM | `>=50.0.0` | X.509 path-building algorithm denial of service with duplicate intermediate certificates. Superset parses leaf database SSL certificates using `load_pem_x509_certificate` and does not build untrusted X.509 certification paths during web request processing. | +| **cryptography** | CVE-2026-69248 | MEDIUM | `>=50.0.0` | NULL cipher null pointer dereference in PKCS#12 parsing (`PKCS12.load_key_and_certificates`). Superset parses PEM X.509 certificates and does not ingest or parse user-supplied PKCS#12 bundles. | +| **cryptography** | GHSA-537c-gmf6-5ccf | HIGH | `>=50.0.2` | Vulnerabilities in OpenSSL bundled in binary wheels. In production container deployments following Option A, the runtime libraries are updated; raw cryptographic primitives are not exposed to untrusted external callers. | +| **msgpack** | GHSA-6v7p-g79w-8964, GHSA-j586-36cw-2gc2 | HIGH | `>=1.2.3` | Utilized internally for SQL Lab asynchronous query result serialization (`RESULTS_BACKEND_USE_MSGPACK`). Raw msgpack byte streams are generated and consumed only within the trusted backend cache boundary. Exploitability requires full cache store compromise. | +| **pyarrow** | CVE-2026-25087 | HIGH | `>=25.0.1` | Used for columnar tabular transformations and CSV/Parquet ingestion by authenticated users. Ingestion pathways are governed by role-based permissions and file size limits. Exploitability is bounded to authorized data uploads. | + +## 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`: `>=50.0.2, <51.0.0` (enforces remediated releases covering PKCS#7, path-building, PKCS#12, and wheel OpenSSL advisories). + - `msgpack`: `>=1.2.3, <1.3` (enforces remediated releases while barring vulnerable 1.0.x through 1.2.2 releases). + - `pyarrow`: `>=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`: + +```dockerfile +FROM apache/superset:latest + +USER root +RUN uv pip install --no-cache-dir --python /app/.venv/bin/python \ Review Comment: Good catch. Updated the Dockerfile snippet in Option A to include \pyopenssl>=26.0.0\ alongside cryptography, pyarrow, and msgpack, matching our pin in \ equirements/base.in\. Added explanatory notes covering the \_lib.GEN_EMAIL\ removal in cryptography 50.x and why older pyOpenSSL releases cause \import OpenSSL\ to fail during Snowflake keypair or google-auth mutual TLS authentication (commit \ -- This is an automated message from the Apache Git Service.
