An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84653 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jenkins (Bitnami): affected from 2.421.0; 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-2026-84653/ (Markdown: https://insights.sbomify.com/CVE-2026-84653/index.md)","id":"CVE-2026-84653","markdown":"https://insights.sbomify.com/CVE-2026-84653/index.md","name":"CVE-2026-84653","record":{"aliases":["BIT-jenkins-2026-84653","GHSA-r4vq-pcpc-w89c","MINI-gxqg-6cmj-pwmr","MINI-jvcg-5467-qrg9","MINI-jvrg-8997-5w69","MINI-jwmm-7v4q-3f2h","MINI-p779-w4r4-2xg2","MINI-vw3h-79rw-2m79","MINI-w48c-gwwq-9ff5"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins automation server","requires_auth":"high_privilege","summary":"Attackers with Overall/Manage permission can modify restricted Appearance configuration options due to missing permission checks in Jenkins.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"jenkins","vendor":"jenkins"}],"cvss":{"score":3.5,"severity":"low","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Jenkins 2.421 through 2.579 (both inclusive), LTS 2.426.1 through 2.568.2 (both inclusive) does not correctly perform permission checks in the Appearance configuration page, allowing attackers with Overall/Manage permission to modify Appearance configuration options they should not have access to.","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":"Missing authorization in Jenkins","id":"CVE-2026-84653","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"jenkins:jenkins","products":["jenkins:jenkins"],"type":"missing_authorization","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Business logic in Jenkins","id":"CVE-2026-84654"},"packages":[{"ecosystem":"Bitnami","fixed":["2.568.3","2.580.0"],"introduced":["2.421.0","2.569.0"],"last_affected":[],"package":"jenkins","purl":"pkg:bitnami/jenkins","source":"BIT-jenkins-2026-84653"}],"prev":{"headline":"Auth bypass in Jenkins","id":"CVE-2026-84652"},"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":"2026-09-04","vendors":["Jenkins Project"]},"summary":"Attackers with Overall/Manage permission can modify restricted Appearance configuration options due to missing permission checks in Jenkins.","url":"https://insights.sbomify.com/CVE-2026-84653/"}
