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-2026-42524 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:htmlpublisher (Maven): affected all versions; fixed in 427.1\n- org.jenkins-ci.plugins:htmlpublisher (Maven): affected all versions; fixed in 427.1\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-2026-42524/ (Markdown: https://insights.sbomify.com/CVE-2026-42524/index.md)","id":"CVE-2026-42524","markdown":"https://insights.sbomify.com/CVE-2026-42524/index.md","name":"CVE-2026-42524","record":{"aliases":["GHSA-f8h4-46xv-h7jj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins HTML Publisher Plugin","requires_auth":"low_privilege","summary":"Stored XSS in Jenkins HTML Publisher Plugin allows attackers with Item/Configure permission to execute scripts via job names or URLs.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"html_publisher","vendor":"jenkins"}],"cvss":{"score":8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Jenkins HTML Publisher Plugin 427 and earlier does not escape job name and URL in the legacy wrapper file, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.","ecosystems":["Maven"],"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":"Jenkins HTML Publisher Plugin has a XSS vulnerability in the legacy wrapper file","id":"CVE-2026-42524","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins Microsoft Entra ID (previously Azure AD) Plugin has an open redirect vulnerability","id":"CVE-2026-42525"},"packages":[{"ecosystem":"Maven","fixed":["427.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:htmlpublisher","purl":null,"source":"GHSA-f8h4-46xv-h7jj"},{"ecosystem":"Maven","fixed":["427.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:htmlpublisher","purl":"pkg:maven/org.jenkins-ci.plugins/htmlpublisher","source":"GHSA-f8h4-46xv-h7jj"}],"prev":{"headline":"Jenkins GitHub Plugin has an XSS vulnerability","id":"CVE-2026-42523"},"products":["Jenkins HTML Publisher Plugin"],"published":"2026-04-29","related":[{"cvss_score":6.5,"headline":"Jenkins HTML Publisher Plugin does not properly sanitize input","id":"CVE-2024-28149","kev_date_added":null,"published":"2024-03-06"},{"cvss_score":6.5,"headline":"Jenkins HTML Publisher Plugin path traversal vulnerability","id":"CVE-2018-1000175","kev_date_added":null,"published":"2018-05-08"},{"cvss_score":6.3,"headline":"Jenkins HTML Publisher Plugin vulnerability displays controller file system information in its logs","id":"CVE-2025-53651","kev_date_added":null,"published":"2025-07-09"},{"cvss_score":5.4,"headline":"Jenkins HTML Publisher Plugin vulnerable to Cross-site Scripting","id":"CVE-2019-10432","kev_date_added":null,"published":"2019-10-01"},{"cvss_score":4.7,"headline":"Jenkins HTML Publisher Plugin Stored XSS vulnerability","id":"CVE-2024-28150","kev_date_added":null,"published":"2024-03-06"},{"cvss_score":4.3,"headline":"Jenkins HTML Publisher Plugin Path traversal vulnerability","id":"CVE-2024-28151","kev_date_added":null,"published":"2024-03-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-04-29","vendors":["Jenkins Project"]},"summary":"Stored XSS in Jenkins HTML Publisher Plugin allows attackers with Item/Configure permission to execute scripts via job names or URLs.","url":"https://insights.sbomify.com/CVE-2026-42524/"}
