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-2021-21641 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:promoted-builds (Maven): affected all versions; fixed in 3.9.1\n- org.jenkins-ci.plugins:promoted-builds (Maven): affected all versions; fixed in 3.9.1\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-2021-21641/ (Markdown: https://insights.sbomify.com/CVE-2021-21641/index.md)","id":"CVE-2021-21641","markdown":"https://insights.sbomify.com/CVE-2021-21641/index.md","name":"CVE-2021-21641","record":{"aliases":["GHSA-5cxw-8v65-76vf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins promoted builds plugin","requires_auth":"none","summary":"Attackers can trick users into promoting builds via CSRF, compromising build integrity in Jenkins environments.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"promoted_builds","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A cross-site request forgery (CSRF) vulnerability in Jenkins promoted builds Plugin 3.9 and earlier allows attackers to to promote builds.","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":"CSRF vulnerability in Jenkins promoted builds Plugin","id":"CVE-2021-21641","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"XML External Entity Reference vulnerability in Jenkins Config File Provider Plugin","id":"CVE-2021-21642"},"packages":[{"ecosystem":"Maven","fixed":["3.9.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:promoted-builds","purl":null,"source":"GHSA-5cxw-8v65-76vf"},{"ecosystem":"Maven","fixed":["3.9.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:promoted-builds","purl":"pkg:maven/org.jenkins-ci.plugins/promoted-builds","source":"GHSA-5cxw-8v65-76vf"}],"prev":{"headline":"View name validation bypass in Jenkins","id":"CVE-2021-21640"},"products":["Jenkins promoted builds Plugin"],"published":"2021-04-07","related":[{"cvss_score":5.4,"headline":"Stored Cross-site Scripting vulnerabilities in Jenkins promoted Builds (Simple) plugin providing additional parameter types","id":"CVE-2022-30965","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":5.4,"headline":"Stored Cross-site Scripting vulnerability in Jenkins Promoted Builds Plugin","id":"CVE-2022-29045","kev_date_added":null,"published":"2022-04-12"},{"cvss_score":5.4,"headline":"Promotion names in Jenkins promoted builds Plugin are not validated when using Job DSL","id":"CVE-2022-29049","kev_date_added":null,"published":"2022-04-12"},{"cvss_score":4.3,"headline":"Jenkins Promoted Builds Plugin allowed unauthorized users to run some promotion processes","id":"CVE-2018-1000114","kev_date_added":null,"published":"2018-03-13"}],"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":"partial"},"state":"PUBLISHED","updated":"2024-10-15","vendors":["Jenkins project"]},"summary":"Attackers can trick users into promoting builds via CSRF, compromising build integrity in Jenkins environments.","url":"https://insights.sbomify.com/CVE-2021-21641/"}
