SCA: security update for github.com/tektoncd/pipeline (GHSA-94jr-7pqp-xhcq)

high Tenable Cloud Security Plugin ID 440680

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. Starting in
 version 1.0.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, the git resolver's revision
 parameter is passed directly as a positional argument to git fetch without any validation that it does not
 begin with a - character. Because git parses flags from mixed positional arguments, an attacker can inject
 arbitrary git fetch flags such as --upload-pack=<binary>. Combined with the validateRepoURL function
 explicitly permitting URLs that begin with / (local filesystem paths), a tenant who can submit
 ResolutionRequest objects can chain these two behaviors to execute an arbitrary binary on the resolver
 pod. The tekton-pipelines-resolvers ServiceAccount holds cluster-wide get/list/watch on all Secrets, so
 code execution on the resolver pod enables full cluster-wide secret exfiltration. Versions 1.0.2, 1.3.4,
 1.6.2, 1.9.3, and 1.11.1 fix the issue. (CVE-2026-40938)

Solution

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