Description
In Progress Kendo UI for jQuery Gantt, the task editor's Parent dropdown renders task titles as HTML. An attacker who can influence a task title shown in the dropdown can cause attacker-controlled markup to execute as JavaScript when a user opens or interacts with the task editor. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected version is 2020.3.915; the latest vulnerable version is 2026.3.1015. The issue is fixed in version 2026.4.1111.
