Starting in version 1.0.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, the Tekton Pipelines git resolver in API mode sends the system-configured Git API token to a user-controlled serverURL when the user omits the token parameter. A tenant with TaskRun or PipelineRun create permission can exfiltrate the shared API token (GitHub PAT, GitLab token, etc.) by pointing serverURL to an attacker-controlled endpoint. Versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1 fix the issue.","state":0,"publishedAt":"2026-04-21T16:26:27.381+00:00","modifiedAt":"2026-05-21T21:20:13.227+00:00","affected":[{"ecosystem":"Vendor product","name":"pipeline","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tektoncd\",\n                    \"product\": \"pipeline\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.0.0, < 1.0.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.2.0, < 1.3.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.4.0, < 1.6.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.7.0, < 1.9.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.10.0, < 1.11.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7,"severity":"HIGH"}],"references":["https://github.com/tektoncd/pipeline/security/advisories/GHSA-wjxp-xrpv-xpff","https://github.com/tektoncd/pipeline/issues/9608","https://github.com/tektoncd/pipeline/issues/9609"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-40161","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-40161","identifiers":["CVE-2026-40161"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
