CVE-2020-29604 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. An issue was discovered in MantisBT before 2.24.4. A missing access check in bug_actiongroup.php allows an attacker (with rights to create new issues) to use the COPY group action to create a clone, including all bugnotes and attachments, of any private issue (i.e., one having Private view status, or belonging to a private Project) via the bug_arr[] parameter. EPSS estimates a 1.14% chance of exploitation in the next 30 days.
