Limit exposure of the affected software until one is available.","what":"CVE-2026-117621 is a vulnerability in Jenkins, published on 28 Oct 2026."},"fix_prompt":"Check this codebase for CVE-2026-117621 and fix it if it is affected.\n\nWhat it is: CVE-2026-117621 is a vulnerability in Jenkins, published on 28 Oct 2026. \nExploitation: There is no known exploitation of CVE-2026-117621 in the wild and no public exploit code.\n\nAffected product: Jenkins. 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-2026-117621/ (Markdown: https://insights.sbomify.com/CVE-2026-117621/index.md)","id":"CVE-2026-117621","markdown":"https://insights.sbomify.com/CVE-2026-117621/index.md","name":"CVE-2026-117621","record":{"aliases":["GHSA-73wp-48jc-x2g4"],"analysis":null,"analysis_generated_by":null,"assigner":"jenkins","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Jenkins 2.587 and earlier, LTS 2.580.1 and earlier computes on the agent the URL of the link shown in the workspace browser for each file and directory, resulting in a cross-site scripting (XSS) vulnerability exploitable by attackers in control of agent processes.","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":"Jenkins 2.587 and earlier, LTS 2.580.1 and earlier computes on the agent the URL of the link shown in the workspace browser for each file an","id":"CVE-2026-117621","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows agents to send exceptions implementing the Stapler HttpResponse interface to the c","id":"CVE-2026-117622"},"packages":[],"prev":{"headline":"Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows attackers with Overall/Read permission to trigger warnings in the \"Manage Old Data","id":"CVE-2026-117620"},"products":["Jenkins"],"published":"2026-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Jenkins Project"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-117621/"}
