Technical details

An information disclosure vulnerability (CWE-200) exists in JFrog Artifactory due to an event-handling weakness. The flaw allows a network-based attacker with low-level authenticated privileges to access sensitive authorization material that should be restricted to higher-privileged users. This occurs under specific conditions related to how the application processes internal events. Successful exploitation could lead to full compromise of confidentiality, integrity, and availability (CVSS 8.8). JFrog has released patches in versions 7.133.21 and 7.146.8 to address this issue.
