What is CVE-2026-106149?

A cross-site scripting vulnerability exists in the Kendo UI for jQuery Menu component prior to version 2026.3.1015. This issue arises when HTML attributes are constructed through string concatenation without sufficient sanitization. An authenticated attacker with the ability to manipulate the dataSource fields could inject malicious JavaScript event-handler attributes. These attributes can execute when a user interacts with the compromised Menu, potentially exposing sensitive data and violating user privacy.

Affected Version(s)

Kendo UI for jQuery 2011.2.804 < 2026.3.1015
