Security Report

3.5

Use Caution3.5High Risk

The server is a plausible evidence-sealing tool with no shell execution, file access, or obfuscation, and its dependencies are standard. The main concern is that the seal tool uploads the full content (up to 10,000 characters) to a third-party Supabase endpoint, while the README states that only the hash leaves the user's machine, so users are misled about what data is transmitted. Additional low-severity items include API key forwarding to an overridable base URL and unencoded hash interpolation in a returned URL. Supply chain analysis found 6 known vulnerabilities in dependencies (0 critical, 4 high severity). Package verification found 1 issue.
