Security Report

3.5
Use Caution3.5High Risk

OpenBrowser is a well-engineered browser automation framework with appropriate authentication and reasonable permission scoping for its developer-tools category. However, several moderate security concerns warrant attention: the MCP server lacks explicit domain allowlisting by default despite providing the feature, code execution via LLM-generated Python introduces inherent risks that are incompletely mitigated, dependency on `cdp-use` (third-party CDP wrapper) and `bubus` (undocumented package) creates supply-chain blindspots, and environment variable handling could be more robust. The framework demonstrates good security awareness (env var usage, storage isolation, profile leasing) but falls short of production-hardened practices in a few critical areas. Supply chain analysis found 20 known vulnerabilities in dependencies (2 critical, 8 high severity). Package verification found 1 issue.
