Status: ModifiedMedium (5.3)—

Coverity versions prior to 2023.3.2 are vulnerable to forced browsing, which exposes authenticated resources to unauthorized actors. The root cause of this vulnerability is an insecurely configured servlet mapping for the underlying Apache Tomcat server. As a result, the downloads directory and its contents are accessible. 5.9 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L/E:P/RL:O/RC:C)
