MantisBT is Vulnerable to Stored HTML Injection/XSS in Clone Issue Form
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Packagist | mantisbt/mantisbt | < 2.28.2 | 2.28.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
When cloning an issue originating from a Project other than the current one, the clone form (bug_report_page.php) prepends the source Project name before the category selector without proper escaping, allowing an attacker able to to inject HTML if they can set the Project's name (which typically requires *manager* or *administrator* access level).
### Impact
Cross-site scripting (XSS).
This is mitigated by Content Security Policy which restricts scripts execution.
### Patches
