Technical details
The Telerik.Documents.AI.AgentTools.Conversion component does not properly sanitize tool arguments, allowing authenticated attackers to use relative file paths (e.g., ../) to traverse outside the configured output directory. Exploitation requires network access and valid (low-privilege) authentication credentials; the attacker can read arbitrary files and overwrite writable files via unsanitized path resolution against the process working directory.
