CVE-2026-82637: Browser-Use Web-UI

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Browser-Use Web-UI: from 2.0.0, up to and including 3.0.0
