golang-github-sigstore-timestamp-authority: Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps
CVE-2026-49835 is fixed in 3 products on 1 platform, first by DEBIAN-CVE-2026-49835, released July 24, 2026. It is not reported as exploited. Patch Radar priority: High.
Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps. Prior to 2.1.0, the global wrapMetrics middleware records raw HTTP request path r.URL.Path and raw HTTP request method r.Method as Prometheus labels for latency and request count metric vectors before routing, allowing an unauthenticated remote attacker to issue requests with random paths such as /api/v1/timestamp/<uuid> or random HTTP methods and create unbounded permanent time-series entries that exhaust memory. This issue is fixed in version 2.1.0.
