CVE-2026-40923 - CERT CVE
ID CVE-2026-40923
Sažetak Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Prior to 1.11.1, a validation bypass in the VolumeMount path restriction allows mounting volumes under restricted /tekton/ internal paths by using .. path traversal components. The restriction check uses strings.HasPrefix without filepath.Clean, so a path like /tekton/home/../results passes validation but resolves to /tekton/results at runtime. This vulnerability is fixed in 1.11.1.
