Summary
MantisBT XSS issue on the view_all_bug_page.php
Details

An XSS issue was discovered in MantisBT before 2.24.2. Improper escaping on view_all_bug_page.php allows a remote attacker to inject arbitrary HTML into the page by saving it into a text Custom Field, leading to possible code execution in the browser of any user subsequently viewing the issue (if CSP settings allow it).

Severity ?
5.4 (Medium)
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
