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.\n\n## Affected\n\n- `tekton_pipelines >= 1.1.0, < 1.3.3`\n- `tekton_pipelines >= 1.4.0, < 1.6.1`\n- `tekton_pipelines >= 1.7.0, < 1.9.2`\n- `tekton_pipelines >= 1.10.0, < 1.10.2`\n- `tekton_pipelines = 1.0.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `tekton_pipelines 1.10.2`","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":52.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
