Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21647 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:electricflow (Maven): affected all versions; fixed in 1.1.18.1\n- org.jenkins-ci.plugins:electricflow (Maven): affected all versions; fixed in 1.1.18.1\n- org.jenkins-ci.plugins:electricflow (Maven): affected from 1.1.19; fixed in 1.1.22\n- org.jenkins-ci.plugins:electricflow (Maven): affected from 1.1.19; fixed in 1.1.22\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-2021-21647/ (Markdown: https://insights.sbomify.com/CVE-2021-21647/index.md)","id":"CVE-2021-21647","markdown":"https://insights.sbomify.com/CVE-2021-21647/index.md","name":"CVE-2021-21647","record":{"aliases":["GHSA-7rx6-4vwv-432g"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins CloudBees CD Plugin","requires_auth":"low_privilege","summary":"Attackers with read permissions can schedule builds without build permissions due to missing authorization checks in the Jenkins CloudBees CD Plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"cloudbees_cd","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"Jenkins CloudBees CD Plugin 1.1.21 and earlier does not perform a permission check in an HTTP endpoint, allowing attackers with Item/Read permission to schedule builds of projects without having Item/Build 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":"Missing permission check in Jenkins CloudBees CD Plugin allows scheduling builds","id":"CVE-2021-21647","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":4,"n_references":2,"next":{"headline":"Cross-Site Request Forgery in Jenkins Credentials Plugin","id":"CVE-2021-21648"},"packages":[{"ecosystem":"Maven","fixed":["1.1.18.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:electricflow","purl":null,"source":"GHSA-7rx6-4vwv-432g"},{"ecosystem":"Maven","fixed":["1.1.18.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:electricflow","purl":"pkg:maven/org.jenkins-ci.plugins/electricflow","source":"GHSA-7rx6-4vwv-432g"},{"ecosystem":"Maven","fixed":["1.1.22"],"introduced":["1.1.19"],"last_affected":[],"package":"org.jenkins-ci.plugins:electricflow","purl":null,"source":"GHSA-7rx6-4vwv-432g"},{"ecosystem":"Maven","fixed":["1.1.22"],"introduced":["1.1.19"],"last_affected":[],"package":"org.jenkins-ci.plugins:electricflow","purl":"pkg:maven/org.jenkins-ci.plugins/electricflow","source":"GHSA-7rx6-4vwv-432g"}],"prev":{"headline":"Remote code execution vulnerability in Jenkins Templating Engine Plugin","id":"CVE-2021-21646"},"products":["Jenkins CloudBees CD Plugin"],"published":"2021-04-21","related":[{"cvss_score":8.1,"headline":"Jenkins CloudBees CD Plugin vulnerable to arbitrary file deletion","id":"CVE-2023-46654","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":6.5,"headline":"Jenkins CloudBees CD Plugin vulnerable to arbitrary file read","id":"CVE-2023-46655","kev_date_added":null,"published":"2023-10-25"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Jenkins project"]},"summary":"Attackers with read permissions can schedule builds without build permissions due to missing authorization checks in the Jenkins CloudBees CD Plugin.","url":"https://insights.sbomify.com/CVE-2021-21647/"}
