What is CVE-2020-25830?

A vulnerability in MantisBT prior to version 2.24.3 allows attackers to input HTML into custom field names. If the Content Security Policy (CSP) settings are not stringent, this can lead to the execution of arbitrary JavaScript when users attempt to update the custom field through the bug_actiongroup_page.php. This injection flaw poses potential security risks by allowing attackers to manipulate the application’s behavior and compromise sensitive data.
