SCA: security update for github.com/sigstore/timestamp-authority/v2 (GHSA-9c54-x2g4-v92j)

medium Tenable Self-Hosted Container Security Plugin ID 444131

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-49835)

Solution

Update the github.com/sigstore/timestamp-authority/v2 library and its related packages to version 2.1.0 or later.
