Critical
Tekton Pipelines git resolver has path traversal that allows reading arbitrary files from the resolver pod
Type: advisorySources: OSV
Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Starting in version 1.0.0 and prior to versions 1.0.1, 1.3.3, 1.6.1, 1.9.2, and 1.10.2, the Tekton Pipelines git resolver is vulnerable to path traversal via the `pathInRepo` parameter. A tenant with permission to create `ResolutionRequests` (e.g. by creating `TaskRuns` or `PipelineRuns` that use the git resolver) can read arbitrary files from the resolver pod's filesystem, including ServiceAccount tokens. The file contents are returned base64-encoded in `resolutionrequest.status.data`. Versions 1.0.1, 1.3.3, 1.6.1, 1.9.2, and 1.10.2 contain a patch.
