An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-24427 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:bitbucket-oauth (Maven): affected all versions; fixed in 0.13\n- org.jenkins-ci.plugins:bitbucket-oauth (Maven): affected all versions; fixed in 0.13\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-2023-24427/ (Markdown: https://insights.sbomify.com/CVE-2023-24427/index.md)","id":"CVE-2023-24427","markdown":"https://insights.sbomify.com/CVE-2023-24427/index.md","name":"CVE-2023-24427","record":{"aliases":["GHSA-x9q4-qwfh-9gjq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Bitbucket OAuth Plugin","requires_auth":"none","summary":"Attackers can hijack user sessions because the plugin fails to invalidate previous sessions upon login, allowing unauthorized access to Jenkins accounts.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"bitbucket_oauth","vendor":"jenkins"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"Jenkins Bitbucket OAuth Plugin 0.12 and earlier does not invalidate the previous session on login.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Session fixation vulnerability in Jenkins Bitbucket OAuth Plugin","id":"CVE-2023-24427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":2,"n_references":1,"next":{"headline":"Cross-site request forgery vulnerability in Jenkins Bitbucket OAuth Plugin","id":"CVE-2023-24428"},"packages":[{"ecosystem":"Maven","fixed":["0.13"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:bitbucket-oauth","purl":null,"source":"GHSA-x9q4-qwfh-9gjq"},{"ecosystem":"Maven","fixed":["0.13"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:bitbucket-oauth","purl":"pkg:maven/org.jenkins-ci.plugins/bitbucket-oauth","source":"GHSA-x9q4-qwfh-9gjq"}],"prev":{"headline":"Insufficient Session Expiration in Jenkins Azure AD Plugin","id":"CVE-2023-24426"},"products":["Jenkins Bitbucket OAuth Plugin"],"published":"2023-01-24","related":[{"cvss_score":7.8,"headline":"Jenkins Bitbucket OAuth Plugin contains Insufficiently Protected Credentials","id":"CVE-2019-10460","kev_date_added":null,"published":"2019-10-23"},{"cvss_score":5.7,"headline":"Cross-site request forgery vulnerability in Jenkins Bitbucket OAuth Plugin","id":"CVE-2023-24428","kev_date_added":null,"published":"2023-01-24"},{"cvss_score":4.3,"headline":"Jenkins Bitbucket OAuth Plugin does not restrict the redirect URL after login","id":"CVE-2026-48924","kev_date_added":null,"published":"2026-05-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-02","vendors":["Jenkins Project"]},"summary":"Attackers can hijack user sessions because the plugin fails to invalidate previous sessions upon login, allowing unauthorized access to Jenkins accounts.","url":"https://insights.sbomify.com/CVE-2023-24427/"}
