An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48919 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:active-directory (Maven): affected all versions; fixed in 2.41.1\n- org.jenkins-ci.plugins:active-directory (Maven): affected all versions; fixed in 2.41.1\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-2026-48919/ (Markdown: https://insights.sbomify.com/CVE-2026-48919/index.md)","id":"CVE-2026-48919","markdown":"https://insights.sbomify.com/CVE-2026-48919/index.md","name":"CVE-2026-48919","record":{"aliases":["GHSA-p2gw-f3rv-82mw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Active Directory Plugin","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary code by sending malicious LDAP referral data to the Jenkins Active Directory Plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"active_directory","vendor":"jenkins"}],"cvss":{"score":6.6,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Jenkins Active Directory Plugin 2.41 and earlier deserializes data from LDAP referrals without validation.","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":"Jenkins Active Directory Plugin deserializes data from LDAP referrals without validation","id":"CVE-2026-48919","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins Email Extension Plugin: Attackers able to control email content may specify `file:` URLs for images to read arbitrary files from Jenkins controller filesystem","id":"CVE-2026-48920"},"packages":[{"ecosystem":"Maven","fixed":["2.41.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":null,"source":"GHSA-p2gw-f3rv-82mw"},{"ecosystem":"Maven","fixed":["2.41.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":"pkg:maven/org.jenkins-ci.plugins/active-directory","source":"GHSA-p2gw-f3rv-82mw"}],"prev":{"headline":"Jenkins Active Directory Plugin follows LDAP referrals by default","id":"CVE-2026-48918"},"products":["Jenkins Active Directory Plugin"],"published":"2026-05-27","related":[{"cvss_score":9.8,"headline":"Improper Authentication in Jenkins Active Directory Plugin","id":"CVE-2020-2299","kev_date_added":null,"published":"2020-11-04"},{"cvss_score":9.8,"headline":"Improper Authentication (empty password) in Jenkins Active Directory Plugin","id":"CVE-2020-2300","kev_date_added":null,"published":"2020-11-04"},{"cvss_score":9.8,"headline":"Authentication cache in Active Directory Jenkins Plugin allows logging in with any password","id":"CVE-2020-2301","kev_date_added":null,"published":"2020-11-04"},{"cvss_score":8.1,"headline":"Jenkins Active Directory Plugin did not verify certificate of AD server","id":"CVE-2017-2649","kev_date_added":null,"published":"2018-07-27"},{"cvss_score":7.4,"headline":"Jenkins Active Directory Plugin Improper certificate validation with StartTLS","id":"CVE-2019-1003009","kev_date_added":null,"published":"2019-02-06"},{"cvss_score":6.6,"headline":"Jenkins Active Directory Plugin follows LDAP referrals by default","id":"CVE-2026-48918","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["Jenkins Project"]},"summary":"Attackers can execute arbitrary code by sending malicious LDAP referral data to the Jenkins Active Directory Plugin.","url":"https://insights.sbomify.com/CVE-2026-48919/"}
