########## docs/admin_docs/security/dependency-vulnerability-remediation.mdx: ########## @@ -0,0 +1,77 @@ +--- +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, CVE-2026-69249, GHSA-537c-gmf6-5ccf, CVE-2026-69248 | HIGH / MEDIUM | `>=50.0.2` | Used primarily for encrypting database connection passwords at rest and parsing operator-supplied SSL certificates. Unauthenticated external input does not traverse PKCS12 parsing routines. Exploitability in standard deployments is considered low. | +| **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 while preventing regressions on PKCS12 and certificate validation flaws). + - `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 \ + "cryptography>=50.0.2" \ + "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 vulnerable code path is unreachably encapsulated behind authentication can be documented and suppressed in `.trivyignore`: + +```text +# Cryptography PKCS12 parsing not exposed to unauthenticated input (issue #45087) Review Comment: Rewrote both the Table 1 row and the `.trivyignore` rationale around cryptography X.509 certificate verifier APIs (`cryptography.x509.verification.PolicyBuilder`). Clarified that Superset parses leaf database certificates using `load_pem_x509_certificate` and does not call cryptography certificate verification or path validation APIs, leaving transport validation to underlying network and database drivers via OpenSSL/Python `ssl`. Also aligned the remediation floor to `>=49.0.0` in the table and updated the summary comment in `requirements/base.in` (commit `0ce5eae61f`). -- This is an automated message from the Apache Git Service.
