{"id":"CVE-2020-2191","aliases":["GHSA-j852-mp82-wv2g"],"url":"https://o3.security/vulnerability/CVE-2020-2191","summary":"Improper permission checks in Jenkins Swarm Plugin","details":"Swarm Plugin adds API endpoints to add or remove agent labels. In Swarm Plugin 3.20 and earlier these only require a global Swarm secret to use, and no regular permission check is performed. This allows users with Agent/Create permission to add or remove labels of any agent.\n\nSwarm Plugin 3.21 requires Agent/Configure permission for the affected agent to these endpoints. It no longer uses the global Swarm secret for these API endpoints.","published":"2020-06-03T13:15:10.617Z","modified":"2026-07-08T20:31:08.915513Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.jenkins-ci.plugins:swarm","fixedVersion":"3.21"}],"fix":{"url":"https://github.com/jenkinsci/swarm-plugin/commit/4d18f98b00e4c84b152d52346fb9ef1a227b1cf7","label":"jenkinsci/swarm-plugin@4d18f98"},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2020/06/03/3"},{"type":"ADVISORY","url":"https://jenkins.io/security/advisory/2020-06-03/#SECURITY-1200"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-2191"},{"type":"WEB","url":"https://github.com/jenkinsci/swarm-plugin/commit/4d18f98b00e4c84b152d52346fb9ef1a227b1cf7"},{"type":"PACKAGE","url":"https://github.com/jenkinsci/swarm-plugin"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T20:31:08.915513Z"}}
