An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84648 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-2026-84648/ (Markdown: https://insights.sbomify.com/CVE-2026-84648/index.md)","id":"CVE-2026-84648","markdown":"https://insights.sbomify.com/CVE-2026-84648/index.md","name":"CVE-2026-84648","record":{"aliases":["BIT-jenkins-2026-84648","GHSA-qgwr-f9q8-fxgq","MINI-4274-mx59-jx46","MINI-44v2-762f-cgrg","MINI-8fvx-738p-8h7r","MINI-cg65-frpq-mrwj","MINI-pmc2-3mmx-jfwx","MINI-pv52-x424-ccqh","MINI-xv34-gqcc-jwjx"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins CI server","requires_auth":"none","summary":"Attackers controlling agent processes can inject malicious scripts into Jenkins system logs, leading to stored XSS and potential session hijacking.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"jenkins","vendor":"jenkins"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the system log viewer does not escape log record metadata (source, level, and timestamp) resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers in control of agent processes.","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":"Cross-site scripting in Jenkins","id":"CVE-2026-84648","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"jenkins:jenkins","products":["jenkins:jenkins"],"type":"xss","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Cross-site request forgery in Jenkins","id":"CVE-2026-84649"},"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-2026-84648"}],"prev":{"headline":"Deserialization in Jenkins","id":"CVE-2026-84647"},"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":"total"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Jenkins Project"]},"summary":"Attackers controlling agent processes can inject malicious scripts into Jenkins system logs, leading to stored XSS and potential session hijacking.","url":"https://insights.sbomify.com/CVE-2026-84648/"}
