What is CVE-2020-29604?

A vulnerability exists in MantisBT versions before 2.24.4 due to a missing access control check in the bug_actiongroup.php file. This issue permits an attacker with permissions to create new issues to exploit the COPY group action. By leveraging this flaw, an attacker can duplicate any private issue, which includes all associated bugnotes and attachments, merely by manipulating thebug_arr[] parameter. This can expose sensitive information, leading to unauthorized access to confidential data stored within private projects or issues.
