Prometheus

v3.5.4Observability

2026年6月18日リンクをコピー

Prometheus v3.5.4 is a security-focused patch: fixes a secret-exposure bug in STACKIT SD and bumps several Go/UI dependencies to patch known CVEs. Upgrade promptly.

• securityRotate STACKIT SD credentials if you use that SD

  The /-/config endpoint was exposing STACKIT service discovery secrets in plaintext. If your Prometheus instance uses STACKIT SD and /-/config was reachable by anyone other than admins, assume those credentials are compromised and rotate them. Upgrade to v3.5.4 immediately, then restrict access to /-/config behind authentication.

• securityUpgrade to patch three Go CVEs in golang.org/x/net and OpenTelemetry

  GO-2026-5026, GO-2026-4918, and GO-2026-4985 are addressed by bumping golang.org/x/net to v0.55.0 and OpenTelemetry to v1.43.0. If you run Prometheus exposed to untrusted network traffic, this upgrade should not wait for your next maintenance window.

• enhancementghcr.io image publishing available as an alternative pull source

  Prometheus images are now also on ghcr.io. If your environment has rate-limit or access issues with Docker Hub, you can switch your image pull source to ghcr.io/prometheus/prometheus without waiting for a feature release.
