Name of the Vulnerable Software and Affected Versions Telerik UI for AJAX versions prior to 2026.2.708

Description When the Telerik.Upload.ConfigurationHashKey is absent and the machineKey is not explicitly configured, the integrity protection for upload metadata may revert to a predictable default key. This allows attackers to forge protected upload metadata, which can be used to facilitate further exploit chains.

Recommendations Update Telerik UI for AJAX to version 2026.2.708 or later. Explicitly configure the machineKey or provide a Telerik.Upload.ConfigurationHashKey to ensure metadata integrity.
