CVE-2026-82637
browser-use web-ui 2.0.0 through 3.0.0 Arbitrary Directory Creation
Description

browser-use web-ui versions 2.0.0 through 3.0.0 fail to validate browser settings paths in run_agent_task, allowing attackers to create directories at arbitrary locations by supplying absolute paths to save_recording_path, save_trace_path, save_agent_history_path, or save_download_path parameters. Attackers can exploit this via the unauthenticated Gradio interface to create directories anywhere the root-running container has write access.
