Details

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: - resolving or closing issues (bug_change_status_page.php) belonging to a project linking said custom field - viewing issues (view_all_bug_page.php) when the custom field is displayed as a column - printing issues (print_all_bug_page.php) when the custom field is displayed as a column

### Impact Cross-site scripting (XSS).

### Patches https://github.com/mantisbt/mantisbt/commit/447a521aae0f82f791b8116a14a20e276df739be
