This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API now only lists upstream and downstream projects that the current user has access to.","published":"2018-01-26T02:29:01.157Z","modified":"2026-10-24T10:30:23.547073705Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.jenkins-ci.main:jenkins-core","fixedVersion":"2.73.2"},{"ecosystem":"Maven","name":"org.jenkins-ci.main:jenkins-core","fixedVersion":"2.84"}],"fix":{"url":"https://github.com/jenkinsci/jenkins/commit/b2083a387a5bdb6f7ee7f7c81a1f6312aca2a558","label":"jenkinsci/jenkins@b2083a3"},"references":[{"type":"ADVISORY","url":"https://jenkins.io/security/advisory/2017-10-11/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-1000400"},{"type":"WEB","url":"https://github.com/jenkinsci/jenkins/commit/b2083a387a5bdb6f7ee7f7c81a1f6312aca2a558"},{"type":"PACKAGE","url":"https://github.com/jenkinsci/jenkins"},{"type":"WEB","url":"https://github.com/jenkinsci/jenkins/blob/6d179998e18adfbaa4e443c7e837135bf36c53d7/test/src/test/java/hudson/model/AbstractProjectTest.java"},{"type":"WEB","url":"https://jenkins.io/security/advisory/2017-10-11"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-24T10:30:23.547073705Z"}}
