Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84671 in the wild and no public exploit code.\n\nAffected product: Jenkins File Parameter 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-2026-84671/ (Markdown: https://insights.sbomify.com/CVE-2026-84671/index.md)","id":"CVE-2026-84671","markdown":"https://insights.sbomify.com/CVE-2026-84671/index.md","name":"CVE-2026-84671","record":{"aliases":["GHSA-ch57-mp3q-j35f"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins File Parameter Plugin","requires_auth":"low_privilege","summary":"Attackers can write files to arbitrary locations on the Jenkins controller, leading to remote code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Jenkins File Parameter Plugin 425.v3fa_801681b_5e and earlier allows writing files to arbitrary locations on the Jenkins controller file system through Stapler data binding, which can lead to remote code execution.","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 File Parameter Plugin","id":"CVE-2026-84671","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 Microsoft Entra ID (previously Azure AD) Plugin","id":"CVE-2026-84672"},"packages":[],"prev":{"headline":"Deserialization in Jenkins Performance Plugin","id":"CVE-2026-84670"},"products":["Jenkins File Parameter 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":"total"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Jenkins Project"]},"summary":"Attackers can write files to arbitrary locations on the Jenkins controller, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-84671/"}
