Executive Summary

This vulnerability affects Progress Kendo UI for jQuery versions from v2023.1.117 up to but not including v2026.3.1015. The FileBrowser and ImageBrowser components improperly render user-controlled file and directory names as HTML without encoding. Attackers can inject malicious scripts via these names, leading to cross-site scripting (XSS) attacks in victims' browsers.

Detection Guidance

Check if your Kendo UI for jQuery version is between v2023.1.117 and prior to v2026.3.1015. Inspect network traffic for FileBrowser or ImageBrowser components rendering user-controlled file or directory names without proper HTML encoding.

Impact Analysis

An attacker could steal sensitive data, hijack user sessions, or perform actions on behalf of users within the affected application. This compromises confidentiality and integrity of data accessible to the app. Users interacting with malicious file names may unknowingly execute attacker scripts.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality principles or HIPAA's safeguards for protected health information. Organizations may face compliance violations, fines, or reputational damage if exploited.

Mitigation Strategies

Upgrade to Kendo UI for jQuery v2026.3.1015 or later. If immediate upgrade is not possible, disable the FileBrowser and ImageBrowser components or implement input validation and output encoding for file and directory names.
