Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84656 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-2026-84656/ (Markdown: https://insights.sbomify.com/CVE-2026-84656/index.md)","id":"CVE-2026-84656","markdown":"https://insights.sbomify.com/CVE-2026-84656/index.md","name":"CVE-2026-84656","record":{"aliases":["BIT-jenkins-2026-84656","GHSA-9v33-56f7-qg5c","MINI-6mxf-xc47-xqwv","MINI-h48h-f224-wr22","MINI-h97w-4ffw-q3g9","MINI-jw3x-652j-6fcv","MINI-rcxv-gmp3-fxc4","MINI-rmvm-m9g9-7578","MINI-xq9f-g9hf-2wq2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins automation server","requires_auth":"low_privilege","summary":"Attackers with basic read permissions can view sensitive build parameters of unauthorized jobs in Jenkins.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"jenkins","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing permission check in Jenkins 2.579 and earlier, LTS 2.568.2 and earlier allows attackers with Item/Read permission on at least one job to read build parameter names and values of jobs they have no 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-2026-84656","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":"Missing authorization in Jenkins","id":"CVE-2026-84657"},"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-2026-84656"}],"prev":{"headline":"Other in Jenkins","id":"CVE-2026-84655"},"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":"2026-09-02","vendors":["Jenkins Project"]},"summary":"Attackers with basic read permissions can view sensitive build parameters of unauthorized jobs in Jenkins.","url":"https://insights.sbomify.com/CVE-2026-84656/"}
