{"id":"CVE-2026-33211","summary":"Tekton Pipelines git resolver has path traversal that allows reading arbitrary files from the resolver pod","details":"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.","aliases":["GHSA-j5q5-j9gm-2w5c","GO-2026-4761"],"modified":"2026-04-10T05:42:39.823275Z","published":"2026-03-23T23:55:54.089Z","related":["CGA-3v45-wr3m-8cgj","SUSE-SU-2026:1135-1"],"database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33211.json","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33211.json"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/10fa538f9a2b6d01c75138f1ed7ba3da0e34687c"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/318006c4e3a5"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/3ca7bc6e6dd1d97f80b84f78370d91edaf023cbd"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/961388fcf3374bc7656d28ab58ca84987e0a75ae"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/b1fee65b88aa969069c14c120045e97c37d9ee5e"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/cdb4e1e97a4f3170f9bc2cbfff83a6c8107bc3db"},{"type":"FIX","url":"https://github.com/tektoncd/pipeline/commit/ec7755031a183b345cf9e64bea0e0505c1b9cb78"},{"type":"ADVISORY","url":"https://github.com/tektoncd/pipeline/security/advisories/GHSA-j5q5-j9gm-2w5c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33211"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tektoncd/pipeline","events":[{"introduced":"d9974e2cce817a43c69789161f0824e05a7572af"},{"fixed":"ec7755031a183b345cf9e64bea0e0505c1b9cb78"}],"database_specific":{"versions":[{"introduced":"1.0.0"},{"fixed":"1.0.1"}]}},{"type":"GIT","repo":"https://github.com/tektoncd/pipeline","events":[{"introduced":"43c0bb99fa768ff711ad92445c43179b93232877"},{"fixed":"10fa538f9a2b6d01c75138f1ed7ba3da0e34687c"}],"database_specific":{"versions":[{"introduced":"1.1.0"},{"fixed":"1.3.3"}]}},{"type":"GIT","repo":"https://github.com/tektoncd/pipeline","events":[{"introduced":"eaf7dc1dca3e314c26d14caff8207026a2dfade7"},{"fixed":"3fb58318e1805be7bdaaafcb23e42ade2edbf59c"}],"database_specific":{"versions":[{"introduced":"1.4.0"},{"fixed":"1.6.1"}]}},{"type":"GIT","repo":"https://github.com/tektoncd/pipeline","events":[{"introduced":"478d30f0a799663216cd225cf826e0b1efdadee3"},{"fixed":"3ca7bc6e6dd1d97f80b84f78370d91edaf023cbd"}],"database_specific":{"versions":[{"introduced":"1.7.0"},{"fixed":"1.9.2"}]}},{"type":"GIT","repo":"https://github.com/tektoncd/pipeline","events":[{"introduced":"9db88e0a3f072ade16ad0d88f1fd6a391281cf39"},{"fixed":"cdb4e1e97a4f3170f9bc2cbfff83a6c8107bc3db"}],"database_specific":{"versions":[{"introduced":"1.10.0"},{"fixed":"1.10.2"}]}}],"versions":["v1.0.0","v1.1.0","v1.10.0","v1.10.1","v1.2.0","v1.3.0","v1.3.1","v1.3.2","v1.4.0","v1.5.0","v1.6.0","v1.7.0","v1.9.0","v1.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33211.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
