CVE-2021-45074Network attack vector

Forced reauthentication via unauthorized OAuth token deletion

Published Mar 2, 2022 · Updated Aug 4, 2024

Broken access control in JFrog Artifactory before 7.29.3 and 6.23.38 allows remote authenticated users to force reauthentication. The OAuth token deletion operation accepts another known user as its target without enforcing sufficient authorization. Low-privileged access plus knowledge of the username and an OAuth token is required; deletion interrupts an active session or requires authentication at the next UI session.
