Source: NVD(opens in a new tab)
Identifier: CVE-2026-82637
Published: August 30, 2026
Record updated: October 9, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.4%

Summary

browser-use web-ui versions 2.0.0 through 3.0.0 do not validate browser settings paths in run_agent_task. An attacker can supply absolute paths to save_recording_path, save_trace_path, save_agent_history_path, or save_download_path and create directories at arbitrary locations. The attack runs through the unauthenticated Gradio interface, and the container runs as root, so directories can be created anywhere it has write access.

Mitigation

The source does not state a fix yet. Check the original advisory for updates.
