An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84663 in the wild and no public exploit code.\n\nAffected product: Jenkins Pipeline: Groovy Libraries 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-2026-84663/ (Markdown: https://insights.sbomify.com/CVE-2026-84663/index.md)","id":"CVE-2026-84663","markdown":"https://insights.sbomify.com/CVE-2026-84663/index.md","name":"CVE-2026-84663","record":{"aliases":["GHSA-xv9v-gwf8-vr97"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Groovy Libraries Plugin","requires_auth":"none","summary":"Attackers can delete shared library caches via CSRF, requiring Jenkins administrators to upgrade the Groovy Libraries Plugin.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A cross-site request forgery (CSRF) vulnerability in Jenkins Pipeline: Groovy Libraries Plugin 798.v5cc688825312 and earlier allows attackers to delete shared library caches.","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":"Cross-site request forgery in Jenkins Pipeline: Groovy Libraries Plugin","id":"CVE-2026-84663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Server-side request forgery in Jenkins GitLab Plugin","id":"CVE-2026-84664"},"packages":[],"prev":{"headline":"Server-side request forgery in Jenkins LDAP Plugin","id":"CVE-2026-84662"},"products":["Jenkins Pipeline: Groovy Libraries 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 delete shared library caches via CSRF, requiring Jenkins administrators to upgrade the Groovy Libraries Plugin.","url":"https://insights.sbomify.com/CVE-2026-84663/"}
