Description Dhananjay Arunesh 2020-10-08 06:37:41 UTC 
An issue was discovered in MantisBT before 2.24.3. Improper escaping of a custom field's name allows an attacker to inject HTML and, if CSP settings permit, achieve execution of arbitrary JavaScript when attempting to update said custom field via bug_actiongroup_page.php.
