{"id":"CVE-2026-33211","aliases":["GHSA-j5q5-j9gm-2w5c","GO-2026-4761"],"url":"https://o3.security/vulnerability/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.","published":"2026-03-23T23:55:54.089Z","modified":"2026-08-05T03:30:40.461008872Z","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/tektoncd/pipeline","fixedVersion":"1.0.1"},{"ecosystem":"Go","name":"github.com/tektoncd/pipeline","fixedVersion":"1.3.3"},{"ecosystem":"Go","name":"github.com/tektoncd/pipeline","fixedVersion":"1.6.1"},{"ecosystem":"Go","name":"github.com/tektoncd/pipeline","fixedVersion":"1.9.2"},{"ecosystem":"Go","name":"github.com/tektoncd/pipeline","fixedVersion":"1.10.2"}],"fix":{"url":"https://github.com/tektoncd/pipeline/commit/10fa538f9a2b6d01c75138f1ed7ba3da0e34687c","label":"tektoncd/pipeline@10fa538"},"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-33211.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10026"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10066"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10125"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10155"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10158"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:21931"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:21932"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:24484"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:6166"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:6170"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-33211"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33211.json"},{"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"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2450554"},{"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-05T03:30:40.461008872Z"}}
