CVE-2026-37236

grpc-gateway v2.28.0 is vulnerable to Incorrect Access Control. The application processes the X-HTTP-Method-Override header in ServeMux.ServeHTTP without restricting allowed methods. When a POST request with Content-Type application/x-www-form-urlencoded includes this header, the request method is rewritten to an arbitrary attacker-supplied value before routing. This allows bypassing method-based access controls enforced by upstream proxies or WAFs.

This update for hauler fixes the following issues:

Changes in hauler:

• update to 2.1.0 (bsc#1265425, CVE-2026-41888):

  • v2.1.0 is a minor release built on the containerd- native foundation laid down in v2.0.0. The headline is that hauler store sync and hauler store add are now fully concurrent, with signature verification pinned to digests and running in parallel too. Alongside that, this release adds an audit trail, a store integrity checker, store-to-manifest generation, private/insecure registry support across every pull path, and a set of fixes for containerd imports, chunked hauls, and Docker Hub reference handling.
  • Notable dependency bumps: Go → 1.26.6; containerd/v2 → 2.3.4; sigstore/cosign/v3 → 3.1.3; sigstore/sigstore → 1.10.9; go-containerregistry → 0.22.0; helm/v4 → 4.2.4; k8s.io libs (apimachinery, api, client-go) → 0.37.0; logrus → 1.10.2; docker/go-metrics → 0.1.0; sigstore/rekor → 1.5.4 (CVE resolution); plus x/mod and go-isatty.

• update to 2.0.3 (bsc#1276124, CVE-2026-72817,CVE-2026-72815,CVE-2026-72816):

Changes for alloy:

Update to version 1.19.2:

• Remove withdrawn lib/pq CVEs from govulncheck
• Add backticks to component name in generated doc output
• BREAKING CHANGE: prometheus.operator.servicemonitors now rejects endpoints that reference local files by default. Set allow_arbitrary_file_access = true to preserve previous behavior.
• prometheus.enrich: Support multi-label matching
• prometheus.relabel: Add opt-in TTL cache mode
• telemetry: Add new metrics for graph connections and pyroscope forwarded entries
• database_observability: Exclude system schemas from MySQL health checks and redact query text in explain_plans
• Add nop receiver to OTel Engine
• Backport dependency upgrades to address GO-2026-6061
