Its main security concerns are SSRF when url is attacker-controlled, path traversal or absolute-path escape through unvalidated subdir/filename_hint values, and unrestricted download size. Validate URL schemes and destinations, constrain path components to safe names beneath cache_root, and enforce a response-size limit.
