Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84667 in the wild and no public exploit code.\n\nAffected product: Jenkins ThinBackup Plugin. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-84667/ (Markdown: https://insights.sbomify.com/CVE-2026-84667/index.md)","id":"CVE-2026-84667","markdown":"https://insights.sbomify.com/CVE-2026-84667/index.md","name":"CVE-2026-84667","record":{"aliases":["GHSA-mm9g-xfj4-25r6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins ThinBackup Plugin","requires_auth":"low_privilege","summary":"Attackers can overwrite backup configuration to redirect writes and include arbitrary files from the Jenkins controller file system in backups.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Jenkins ThinBackup Plugin 2.1.4 and earlier allows overwriting the plugin's backup configuration through Stapler data binding, allowing attackers to redirect backup writes to an attacker-specified directory and to include arbitrary files from the Jenkins controller file system in backups.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path traversal in Jenkins ThinBackup Plugin","id":"CVE-2026-84667","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in Jenkins SAML Plugin","id":"CVE-2026-84668"},"packages":[],"prev":{"headline":"Path traversal in Jenkins Job Configuration History Plugin","id":"CVE-2026-84666"},"products":["Jenkins ThinBackup Plugin"],"published":"2026-09-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-02","vendors":["Jenkins Project"]},"summary":"Attackers can overwrite backup configuration to redirect writes and include arbitrary files from the Jenkins controller file system in backups.","url":"https://insights.sbomify.com/CVE-2026-84667/"}
