SCA: security update for github.com/tektoncd/pipeline (GHSA-rx35-6rhx-7858)

medium Tenable Self-Hosted Container Security Plugin ID 440683

Description

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

- 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. (CVE-2026-40923)

Solution

Update the github.com/tektoncd/pipeline library and its related packages to version 1.0.2 or later.
