Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84652 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jenkins (Bitnami): affected all versions; fixed in 2.568.3, 2.580.0\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-2026-84652/ (Markdown: https://insights.sbomify.com/CVE-2026-84652/index.md)","id":"CVE-2026-84652","markdown":"https://insights.sbomify.com/CVE-2026-84652/index.md","name":"CVE-2026-84652","record":{"aliases":["BIT-jenkins-2026-84652","GHSA-42rh-v5qm-8p5w","MINI-6xvq-q6vm-j2m2","MINI-jgx2-jxhc-3v7j","MINI-q5mp-q372-5q59","MINI-v42j-hq2j-c73r","MINI-x3gq-fqxc-c2h2","MINI-x5hv-25xw-pc3v","MINI-x99m-4468-qrf3"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins automation server","requires_auth":"low_privilege","summary":"Attackers can hijack user sessions by exploiting missing session rotation during 'remember me' authentication, leading to unauthorized access.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"jenkins","vendor":"jenkins"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, Jenkins does not rotate the session when a user is authenticated via the \"remember me\" cookie, allowing attackers able to serve content on the same site as Jenkins to set a known session cookie in the victim's browser, which after the victim authenticates via the \"remember me\" cookie, grants the attacker access to Jenkins as that user.","ecosystems":["Bitnami"],"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":"Auth bypass in Jenkins","id":"CVE-2026-84652","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"jenkins:jenkins","products":["jenkins:jenkins"],"type":"auth_bypass","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Missing authorization in Jenkins","id":"CVE-2026-84653"},"packages":[{"ecosystem":"Bitnami","fixed":["2.568.3","2.580.0"],"introduced":["0","2.569.0"],"last_affected":[],"package":"jenkins","purl":"pkg:bitnami/jenkins","source":"BIT-jenkins-2026-84652"}],"prev":{"headline":"Missing authorization in Jenkins","id":"CVE-2026-84651"},"products":["Jenkins"],"published":"2026-09-02","related":[{"cvss_score":9.8,"headline":"Jenkins Command Line Interface (CLI) Path Traversal","id":"CVE-2024-23897","kev_date_added":"2024-08-19","published":"2024-01-24"},{"cvss_score":9.8,"headline":"Jenkins Stapler Web Framework Deserialization of Untrusted Data","id":"CVE-2018-1000861","kev_date_added":"2022-02-10","published":"2018-12-10"},{"cvss_score":9.8,"headline":"Jenkins Remote Code Execution","id":"CVE-2017-1000353","kev_date_added":"2025-10-02","published":"2018-01-29"},{"cvss_score":7.5,"headline":"Jenkins User Interface (UI) Information Disclosure","id":"CVE-2015-5317","kev_date_added":"2023-05-12","published":"2015-11-25"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins","id":"CVE-2021-21690","kev_date_added":null,"published":"2021-11-04"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins","id":"CVE-2021-21691","kev_date_added":null,"published":"2021-11-04"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins","id":"CVE-2021-21692","kev_date_added":null,"published":"2021-11-04"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-09-03","vendors":["Jenkins Project"]},"summary":"Attackers can hijack user sessions by exploiting missing session rotation during 'remember me' authentication, leading to unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-84652/"}
