CVE-2026-106162 · Severity: medium · CVSS 4.7 · Published 2026-10-15

Progress Kendo UI for jQuery is a JavaScript library used to build interactive web applications. The FileManager component, which provides file browser functionality, fails to properly encode item names when displaying drag hints during file drag-and-drop operations. An attacker who can control file or folder names can inject malicious code that executes in users' browsers when they drag items, potentially compromising sensitive data.

## How to fix

- Fixed in 2026.3.1015

Restrict item-name metadata to trusted sources or disable FileManager drag-and-drop through configuration. A temporary JavaScript override is available that HTML-encodes item names in drag hints, but must be tested thoroughly for drag-and-drop side effects before deployment, and upgrading is the preferred solution.

## Technical details

A cross-site scripting (XSS) vulnerability exists in the FileManager component's drag hint rendering. While item names are HTML-encoded in the list view, the drag-and-drop hint renders the same names as unencoded HTML, allowing event handler injection. An attacker with control over item-name metadata can execute arbitrary JavaScript in a user's browser when the user drags an affected item. The vulnerability requires user interaction (dragging) and attacker-controlled item names.
