**Name of the Vulnerable Software and Affected Versions** Highlighting Code Block versions prior to 2.2.1 **Description** Stored Cross-Site Scripting occurs in the admin settings due to insufficient input sanitization and output escaping. Authenticated attackers with administrator-level permissions or higher can inject arbitrary web scripts into pages. These scripts execute when a user accesses the affected page. This issue specifically impacts multi-site installations and environments where `unfiltered html` has been disabled. **Recommendations** Update to a version newer than 2.2.0.
