CVE-2026-82637Public exploitNetwork attack vectorHinoki check available

Unauthenticated directory creation via unvalidated save paths

Published Aug 30, 2026 · Updated Aug 30, 2026

Path injection in Browser Use Web UI 2.0.0 through 3.0.0 allows remote attackers to create arbitrary directories through Gradio. The run_agent_task function passes four attacker-controlled save paths directly to os.makedirs without normalization, allowlisting, or containment validation. The unauthenticated interface reaches these calls before LLM initialization, so no valid API key is needed and container write permissions bound the result.
