Technical details
The Menu component's rendering functions (itemCssAttributes, imageCssAttributes, contentCssAttributes) concatenate dataSource field values into HTML attribute strings without sanitization, allowing injection of event-handler attributes (CWE-80). An authenticated attacker who can control dataSource values can inject payload like onclick= to achieve arbitrary JavaScript execution when users interact with the menu. A fix is available in version 2026.3.1015 and later.
