Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-24399 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:oic-auth (Maven): affected all versions; fixed in 4.453.v4d7765c854f4\n- org.jenkins-ci.plugins:oic-auth (Maven): affected all versions; fixed in 4.453.v4d7765c854f4\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-2025-24399/ (Markdown: https://insights.sbomify.com/CVE-2025-24399/index.md)","id":"CVE-2025-24399","markdown":"https://insights.sbomify.com/CVE-2025-24399/index.md","name":"CVE-2025-24399","record":{"aliases":["GHSA-q9cm-88jx-3vfw"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Jenkins OpenID Connect Plugin","requires_auth":"low_privilege","summary":"Attackers can bypass authentication and gain administrator access by exploiting case-insensitive username handling in Jenkins OpenID Connect plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"openid_connect_authentication","vendor":"jenkins"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"Jenkins OpenId Connect Authentication Plugin 4.452.v2849b_d3945fa_ and earlier, except 4.438.440.v3f5f201de5dc, treats usernames as case-insensitive, allowing attackers on Jenkins instances configured with a case-sensitive OpenID Connect provider to log in as any user by providing a username that differs only in letter case, potentially gaining administrator access to Jenkins.","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":"Improper handling of case sensitivity in Jenkins OpenId Connect Authentication Plugin","id":"CVE-2025-24399","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":2,"n_references":1,"next":{"headline":"Cache confusion in Jenkins Eiffel Broadcaster Plugin","id":"CVE-2025-24400"},"packages":[{"ecosystem":"Maven","fixed":["4.453.v4d7765c854f4"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:oic-auth","purl":null,"source":"GHSA-q9cm-88jx-3vfw"},{"ecosystem":"Maven","fixed":["4.453.v4d7765c854f4"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:oic-auth","purl":"pkg:maven/org.jenkins-ci.plugins/oic-auth","source":"GHSA-q9cm-88jx-3vfw"}],"prev":{"headline":"Bitbucket Server Integration Plugin allows bypassing CSRF protection for any URL","id":"CVE-2025-24398"},"products":["Jenkins OpenId Connect Authentication Plugin"],"published":"2025-01-22","related":[{"cvss_score":8.8,"headline":"Session fixation vulnerability in Jenkins OpenId Connect Authentication Plugin","id":"CVE-2024-52553","kev_date_added":null,"published":"2024-11-13"},{"cvss_score":8.8,"headline":"Session fixation vulnerability in Jenkins OpenId Connect Authentication Plugin","id":"CVE-2023-24424","kev_date_added":null,"published":"2023-01-24"},{"cvss_score":8.1,"headline":"Jenkins OpenId Connect Authentication Plugin lacks audience claim validation","id":"CVE-2024-47806","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":8.1,"headline":"Jenkins OpenId Connect Authentication Plugin lacks issuer claim validation","id":"CVE-2024-47807","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":6.1,"headline":"Open redirect vulnerability in Jenkins OpenId Connect Authentication Plugin","id":"CVE-2023-50771","kev_date_added":null,"published":"2023-12-13"},{"cvss_score":4.3,"headline":"Jenkins OpenId Connect Authentication Plugin showed plain text client secret in configuration form","id":"CVE-2019-1003021","kev_date_added":null,"published":"2019-02-06"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-18","vendors":["Jenkins Project"]},"summary":"Attackers can bypass authentication and gain administrator access by exploiting case-insensitive username handling in Jenkins OpenID Connect plugin.","url":"https://insights.sbomify.com/CVE-2025-24399/"}
