What is CVE-2026-6022?

The Telerik UI for AJAX, specifically RadAsyncUpload, is vulnerable to uncontrolled resource consumption due to inadequate cumulative size enforcement during chunk reassembly of file uploads. This can allow uploads to surpass the intended maximum file size, which could lead to significant disk space exhaustion on the server, potentially disrupting application performance and service availability. It's crucial for users to update to version 2026.1.421 or later to mitigate this vulnerability.
