Official description

In Progress® Kendo® UI for jQuery prior to v2026.3.1015, the Menu component constructs HTML attributes from bound dataSource fields by string concatenation without proper neutralization. An attacker with low privileges who can control these fields can inject JavaScript event-handler attributes that execute when a user interacts with the affected Menu, compromising the confidentiality and integrity of data accessible in the user's browser context.
