Security Report

4.2
Use Caution4.2High Risk

Fluxmail is a substantial self-hosted email infrastructure server with generally sound security practices. Authentication and authorization are present and reasonable, with permission scoping via profiles. However, several code quality and operational concerns warrant attention: environment variable credential handling lacks comprehensive validation, some password/secret flows rely on process.env without explicit safeguards, broad exception handling in key sections could mask errors, and the codebase's complexity around credential storage and account management introduces moderate risk if misconfigured by operators. Supply chain analysis found 4 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue (1 critical, 0 high severity).
