Summary
A vulnerability in browser-use web-ui versions 2.0.0 through 3.0.0 fails to validate file paths in the run_agent_task function, allowing attackers to create directories anywhere on a system by providing absolute paths (full file locations starting from the root) through parameters like save_recording_path. Since the Gradio interface (a web platform for sharing AI tools) doesn't require authentication, attackers can exploit this without logging in.
