Technical details
Uncontrolled recursion, infinite loops, and inefficient algorithmic complexity in RadPdfProcessing and AI connector modules (Telerik.Windows.Documents.AIConnector, Telerik.Documents.AIConnector, Telerik.Documents.AI.RAG) allow unauthenticated network attackers to trigger resource exhaustion. Exploitation requires sending a crafted PDF or document text to vulnerable processing functions; no authentication or user interaction is required, resulting in denial of service via process termination or hang.
