No public exploit code is tracked. It is rated CVSS 7.1 (high) and affects Kendo UI for jQuery; fixed in 2026.4.1110. ## Summary Progress Software's Kendo UI for jQuery has a cross-site scripting flaw in its PropertyGrid component, which does not encode bound property values or item descriptions by default. An attacker can reach it remotely, without logging in, by supplying a value the grid displays, and a user who views the grid then runs the attacker's JavaScript in their browser, which could expose or alter data available there. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - Progress Software Kendo UI for jQuery: from 2026.3.1015, fixed in 2026.4.1110 ## Description In Progress Kendo UI for jQuery versions 2026.3.1015 up to, but not including, 2026.4.1110, PropertyGrid does not encode bound property values and items[].description in its default configuration. An attacker who can influence either value can cause JavaScript to execute when a user views the grid. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context.
