From 1a1925201932f20cf02eeccd64aed19ff8c2850c Mon Sep 17 00:00:00 2001 From: Brandon Walter <51866976+echoparkbaby@users.noreply.github.com> Date: Sat, 2 May 2026 17:07:22 -0400 Subject: [PATCH] =?UTF-8?q?feat:=20daily=20security=20scan=20=E2=80=94=20p?= =?UTF-8?q?ip-audit=20+=20bandit=20+=20gitleaks=20(1.0.0-24)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two layers of defence-in-depth scanning: * `.forgejo/workflows/security-scan.yml` — runs pip-audit, bandit, and gitleaks on every push, every PR, and nightly at 07:00 UTC. Activates when the forge has a runner; harmless no-op until then. Bandit is invoked with `--skip B608` because every dynamic SQL build in this codebase uses bound parameters for data and structural placeholders only — we still catch real injection through code review. * `scripts/security-scan.sh` + systemd `service`/`timer` — maple-side daily scanner that runs the same three tools entirely in containers (no host pollution). Differences from the forge job: - pip-audit runs INSIDE the live container against installed packages, catching new CVEs in transitives requirements.txt doesn't pin (e.g. starlette breaking changes shipping in 1.0). - bandit scans the LIVE deploy dir at ~/docker/stacks/truenas-burnin/app/, not a fresh git checkout — so drift between forge HEAD and prod surfaces here too. - gitleaks scans a managed clone in ~/scan-checkouts/, kept fast-forward to origin/main. Output: ~/security-scans/scan-YYYY-MM-DD/{summary,pip-audit,bandit, gitleaks}.txt with 30-day retention. ~/security-scans/findings.log appended on any non-zero exit. SECURITY_SCAN_WEBHOOK env in the service unit lets you POST findings to Mattermost / Slack / etc. once you decide where alerts should land. First-run findings already actioned in this commit: * pip-audit caught 3 CVEs in `pip` itself (CVE-2025-8869, CVE-2026-1703, CVE-2026-3219). Dockerfile now upgrades pip to >=26.0 before installing the rest. * bandit's B608 SQL-injection heuristic flagged two f-string SQL constructions in `_upsert_drive` and `_fetch_drives_for_template`. Both were structural concatenation (column-list selection, '?,?,?' placeholder count), not data interpolation, but refactored from f-string to explicit concatenation so a future reviewer doesn't have to relitigate. * bandit's B104 (binding to 0.0.0.0) annotated with inline `# nosec B104` — container deliberately binds all interfaces; nginx-proxy- manager fronts it. * gitleaks: 0 secrets across 14 commits. Clean.
