Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84659 in the wild and no public exploit code.\n\nAffected product: Jenkins Script Security 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-2026-84659/ (Markdown: https://insights.sbomify.com/CVE-2026-84659/index.md)","id":"CVE-2026-84659","markdown":"https://insights.sbomify.com/CVE-2026-84659/index.md","name":"CVE-2026-84659","record":{"aliases":["GHSA-fc8j-cp67-6ww3"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Script Security Plugin","requires_auth":"low_privilege","summary":"Attackers can bypass sandbox restrictions by disabling global sandbox enforcement due to missing permission checks in the Jenkins Script Security Plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"script_security","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Jenkins Script Security Plugin 1412.v7737b_3405f86 and earlier does not enforce a permission check in the method that controls the \"Force the use of the sandbox globally in the system\" setting, allowing attackers to disable it through Stapler data binding.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Missing authorization in Jenkins Script Security Plugin","id":"CVE-2026-84659","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Jenkins Pipeline: Build Step Plugin","id":"CVE-2026-84660"},"packages":[],"prev":{"headline":"Information disclosure in Jenkins Script Security Plugin","id":"CVE-2026-84658"},"products":["Jenkins Script Security Plugin"],"published":"2026-09-02","related":[{"cvss_score":9.9,"headline":"Jenkins Script Security Plugin Sandbox Bypass","id":"CVE-2019-1003029","kev_date_added":"2022-04-25","published":"2019-03-08"},{"cvss_score":9.9,"headline":"Sandbox bypass vulnerabilities in Jenkins Script Security Plugin and in Pipeline: Groovy Plugin","id":"CVE-2022-43401","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":9.9,"headline":"Jenkins Script Security Plugin sandbox bypass vulnerability","id":"CVE-2022-43403","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":9.9,"headline":"Sandbox bypass vulnerabilities in Jenkins Script Security Plugin and in Pipeline: Groovy Plugin","id":"CVE-2022-43404","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":9.9,"headline":"Sandbox bypass vulnerability in Jenkins Script Security Plugin","id":"CVE-2020-2279","kev_date_added":null,"published":"2020-09-23"},{"cvss_score":9.9,"headline":"Improper Control of Generation of Code in Jenkins Script Security Plugin","id":"CVE-2019-10431","kev_date_added":null,"published":"2019-10-01"},{"cvss_score":9.8,"headline":"Jenkins Script Security Plugin has sandbox bypass vulnerability involving crafted constructor bodies","id":"CVE-2024-34144","kev_date_added":null,"published":"2024-05-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-02","vendors":["Jenkins Project"]},"summary":"Attackers can bypass sandbox restrictions by disabling global sandbox enforcement due to missing permission checks in the Jenkins Script Security Plugin.","url":"https://insights.sbomify.com/CVE-2026-84659/"}
