CVE-2026-33211— Tekton Pipelines git resolver has path traversal that allows reading arbitrary files from the resolver pod

Tekton Pipelines git resolver has path traversal that allows reading arbitrary files from the resolver pod

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.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N

对路径名的限制不恰当(路径遍历)

Tekton Pipelines 路径遍历漏洞

Tekton Pipelines是Tekton开源的一个云原生管道。 Tekton Pipelines 1.0.1之前版本、1.3.3之前版本、1.6.1之前版本、1.9.2之前版本和1.10.2之前版本存在路径遍历漏洞，该漏洞源于git解析器存在路径遍历问题，可能导致读取解析器Pod文件系统中的任意文件。
