Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84654 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-2026-84654/ (Markdown: https://insights.sbomify.com/CVE-2026-84654/index.md)","id":"CVE-2026-84654","markdown":"https://insights.sbomify.com/CVE-2026-84654/index.md","name":"CVE-2026-84654","record":{"aliases":["BIT-jenkins-2026-84654","GHSA-jrvc-6cvv-qqx5","MINI-2pfg-4jqg-cjf2","MINI-5949-vcf9-jqrm","MINI-7f8v-jwqv-h4mw","MINI-929j-6hgm-36pw","MINI-977f-hg4p-76fv","MINI-p4xh-ppjp-xgv4","MINI-q59h-vrp9-rpgc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins automation server","requires_auth":"low_privilege","summary":"Attackers can modify global public static fields via form data binding, potentially altering Jenkins instance behavior and escalating privileges.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-472","name":"External Control of Assumed-Immutable Web Parameter"}],"description":"In Stapler 2107.v8dfcb_e8ed317 and earlier, except 2088.2093.vd7c3e58008a_6, included in Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, form data binding allows setting public static fields of the bound configuration object, allowing attackers who can submit configuration forms to modify public static fields of the configuration objects those forms are bound to, resulting in changes that apply globally to the Jenkins instance.","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":"Business logic in Jenkins","id":"CVE-2026-84654","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Other in Jenkins","id":"CVE-2026-84655"},"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-2026-84654"}],"prev":{"headline":"Missing authorization in Jenkins","id":"CVE-2026-84653"},"products":["Jenkins"],"published":"2026-09-02","related":[],"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":"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 can modify global public static fields via form data binding, potentially altering Jenkins instance behavior and escalating privileges.","url":"https://insights.sbomify.com/CVE-2026-84654/"}
