Patch vulnerable transitive dependencies across all three compiled
binaries in the Docker image (backend, Caddy, CrowdSec):
- go-jose/v3 and v4: JOSE/JWT validation bypass (CVE-2026-34986)
- otel/sdk: resource leak in OpenTelemetry SDK (CVE-2026-39883)
- pgproto3/v2: buffer overflow via pgx/v4 bump (CVE-2026-32286)
- AWS SDK v2: event stream injection in CrowdSec deps (GHSA-xmrv-pmrh-hhx2)
- OTel HTTP exporters: request smuggling (CVE-2026-39882)
- gRPC: bumped to v1.80.0 for transitive go-jose/v4 resolution
All Dockerfile patches include Renovate annotations for automated
future tracking. Renovate config extended to cover Go version and
GitHub Action refs in skill example workflows, preventing version
drift in non-CI files. SECURITY.md updated with pre-existing Alpine
base image CVE (no upstream fix available).
Nightly Go stdlib CVEs (1.26.1) self-heal on next development sync;
example workflow pinned to 1.26.2 for correctness.
