MantisBT is Vulnerable to Stored XSS in Saved-Filter Owner Column
Incorrect escaping of a saved filter's owner allows an attacker to inject arbitrary HTML on systems where $g_show_user_realname = ON. ### Impact Cross-site scripting (XSS). Note that By default, only users with *Manager* access level or above can save their filters publicly ### Patches - 44f490bcf20fd491c1b8f3fc9dd041d8c2a30010 ### Workarounds - Prevent display of users' real name (set `$g_ show_user_realname = OFF;` in configuration) - Restrict ability to store filters (set $`g_stored_query_create_threshold` / $`g_stored_query_create_shared_threshold` to `NOBODY` ### Credits Thanks to siunam (Tang Cheuk Hei) for discovering and responsibly reporting the issue.
