Security Report

3.4
Use Caution3.4High Risk

MailCannon is an email outreach platform with reasonable authentication on most endpoints, but has several security concerns that warrant attention. Public endpoints lack proper input validation and error handling, sensitive tokens are stored in environment variables without clear protection guarantees, and the OAuth implementation uses in-memory state storage that could be lost in multi-instance deployments. Additionally, there are potential authorization bypass risks and insufficient validation of user-provided data in critical operations. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 1 high severity).
