Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33211 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/tektoncd/pipeline (Go): affected from 1.0.0; fixed in 1.0.1, 1.3.3, 1.6.1, 1.9.2, 1.11.1\n- github.com/tektoncd/pipeline (Go): affected from 1.0.0; fixed in 1.0.1\n- github.com/tektoncd/pipeline (Go): affected from 1.0.0; fixed in 1.0.1\n- github.com/tektoncd/pipeline (Go): affected from 1.1.0; fixed in 1.3.3\n- github.com/tektoncd/pipeline (Go): affected from 1.1.0; fixed in 1.3.3\n- github.com/tektoncd/pipeline (Go): affected from 1.10.0; fixed in 1.10.2\n- github.com/tektoncd/pipeline (Go): affected from 1.10.0; fixed in 1.10.2\n- github.com/tektoncd/pipeline (Go): affected from 1.4.0; fixed in 1.6.1\n- github.com/tektoncd/pipeline (Go): affected from 1.4.0; fixed in 1.6.1\n- github.com/tektoncd/pipeline (Go): affected from 1.7.0; fixed in 1.9.2\n- github.com/tektoncd/pipeline (Go): affected from 1.7.0; fixed in 1.9.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-33211/ (Markdown: https://insights.sbomify.com/CVE-2026-33211/index.md)","id":"CVE-2026-33211","markdown":"https://insights.sbomify.com/CVE-2026-33211/index.md","name":"CVE-2026-33211","record":{"aliases":["CLEANSTART-2026-BZ35157","GHSA-j5q5-j9gm-2w5c","GO-2026-4761"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Tekton Pipelines git resolver","requires_auth":"low_privilege","summary":"Attackers with ResolutionRequest creation permissions can read arbitrary files, including ServiceAccount tokens, from the Tekton git resolver pod.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tekton_pipelines","vendor":"linuxfoundation"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Tekton Pipelines git resolver has path traversal that allows reading arbitrary files from the resolver pod","id":"CVE-2026-33211","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":11,"n_references":8,"next":{"headline":"Weblate: Improper access control for pending tasks in API","id":"CVE-2026-33212"},"packages":[{"ecosystem":"Go","fixed":["1.0.1","1.3.3","1.6.1","1.9.2","1.11.1"],"introduced":["1.0.0","1.1.0","1.4.0","1.7.0","1.10.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":"pkg:golang/github.com/tektoncd/pipeline","source":"GO-2026-4761"},{"ecosystem":"Go","fixed":["1.0.1"],"introduced":["1.0.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":null,"source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.0.1"],"introduced":["1.0.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":"pkg:golang/github.com/tektoncd/pipeline","source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.3.3"],"introduced":["1.1.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":null,"source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.3.3"],"introduced":["1.1.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":"pkg:golang/github.com/tektoncd/pipeline","source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.10.2"],"introduced":["1.10.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":null,"source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.10.2"],"introduced":["1.10.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":"pkg:golang/github.com/tektoncd/pipeline","source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.6.1"],"introduced":["1.4.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":null,"source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.6.1"],"introduced":["1.4.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":"pkg:golang/github.com/tektoncd/pipeline","source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.9.2"],"introduced":["1.7.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":null,"source":"GHSA-j5q5-j9gm-2w5c"},{"ecosystem":"Go","fixed":["1.9.2"],"introduced":["1.7.0"],"last_affected":[],"package":"github.com/tektoncd/pipeline","purl":"pkg:golang/github.com/tektoncd/pipeline","source":"GHSA-j5q5-j9gm-2w5c"}],"prev":{"headline":"Ruby JSON has a format string injection vulnerability","id":"CVE-2026-33210"},"products":["pipeline"],"published":"2026-03-23","related":[{"cvss_score":7.7,"headline":"Tekton Pipelines: Git resolver API mode leaks system-configured API token to user-controlled serverURL","id":"CVE-2026-40161","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":7.5,"headline":"Tekton Pipelines: Git Resolver Unsanitized Revision Parameter Enables git Argument Injection Leading to RCE","id":"CVE-2026-40938","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":6.5,"headline":"Tekton Pipelines: VerificationPolicy regex pattern bypass via substring matching","id":"CVE-2026-25542","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":6.5,"headline":"Tekton Pipelines: HTTP Resolver Unbounded Response Body Read Enables Denial of Service via Memory Exhaustion","id":"CVE-2026-40924","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":6.5,"headline":"Tekton Pipelines: Controller can panic when setting long resolver names in TaskRun/PipelineRun","id":"CVE-2026-33022","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":5.4,"headline":"Tekton Pipelines: VolumeMount path restriction bypass via missing filepath.Clean in /tekton/ check","id":"CVE-2026-40923","kev_date_added":null,"published":"2026-04-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-07","vendors":["tektoncd"]},"summary":"Attackers with ResolutionRequest creation permissions can read arbitrary files, including ServiceAccount tokens, from the Tekton git resolver pod.","url":"https://insights.sbomify.com/CVE-2026-33211/"}
