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-2026-117618/ (Markdown: https://insights.sbomify.com/CVE-2026-117618/index.md)","id":"CVE-2026-117618","markdown":"https://insights.sbomify.com/CVE-2026-117618/index.md","name":"CVE-2026-117618","record":{"aliases":["GHSA-vrqw-5jr7-wx5r"],"analysis":null,"analysis_generated_by":null,"assigner":"jenkins","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In Jenkins 2.587 and earlier, LTS 2.580.1 and earlier, the HTTP endpoint for creating the first user account does not check whether the setup wizard has been completed, resulting in a race condition that allows unauthenticated attackers to create an administrator account while the initial user account is being replaced.","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":"In Jenkins 2.587 and earlier, LTS 2.580.1 and earlier, the HTTP endpoint for creating the first user account does not check whether the setu","id":"CVE-2026-117618","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 requests authenticated using HTTP Basic authentication, including with an API toke","id":"CVE-2026-117619"},"packages":[],"prev":{"headline":"Jenkins 2.587 and earlier, LTS 2.580.1 and earlier checks for symbolic links in the path of an extracted file only before creating its paren","id":"CVE-2026-117617"},"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-2026-117618/"}
