What happened

Multiple Prometheus releases (notably 3.5.5, 3.13.0 LTS, 3.12.0 and 3.5.4) address several security issues in the UI and dependencies and fix server-side issues. Remediations include bumping sanitize-html to mitigate cross-site scripting (CVE-2026-44990 and CVE-2026-53606), fixing a plaintext secret exposure in STACKIT service discovery (GHSA-39j6-789q-qxvh), rejecting oversized snappy-compressed remote-write payloads (DoS mitigation), and upgrading golang.org/x/net and OpenTelemetry to resolve multiple Go advisories (GO-2026-5026, GO-2026-4918, GO-2026-4985). Also includes changes to stop C/I
