Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84670 in the wild and no public exploit code.\n\nAffected product: Jenkins Performance 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-2026-84670/ (Markdown: https://insights.sbomify.com/CVE-2026-84670/index.md)","id":"CVE-2026-84670","markdown":"https://insights.sbomify.com/CVE-2026-84670/index.md","name":"CVE-2026-84670","record":{"aliases":["GHSA-v45c-jr4p-q7x2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Performance Plugin","requires_auth":"low_privilege","summary":"Attackers with Item/Configure permission can execute arbitrary code on the Jenkins controller via unsafe deserialization of cached performance reports.","user_interaction":"not_required","vuln_class":"deserialization"},"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-502","name":"Deserialization of Untrusted Data"}],"description":"Jenkins Performance Plugin 1015.v09ca_52b_3370e and earlier does not restrict the classes that can be instantiated when deserializing cached performance reports stored in the build directory on the Jenkins controller, allowing attackers with Item/Configure permission to execute arbitrary code on the Jenkins controller.","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":"Deserialization in Jenkins Performance Plugin","id":"CVE-2026-84670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Jenkins File Parameter Plugin","id":"CVE-2026-84671"},"packages":[],"prev":{"headline":"Path traversal in Jenkins Allure Plugin","id":"CVE-2026-84669"},"products":["Jenkins Performance 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 with Item/Configure permission can execute arbitrary code on the Jenkins controller via unsafe deserialization of cached performance reports.","url":"https://insights.sbomify.com/CVE-2026-84670/"}
