Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Attackers could bypass email verification expiry or tamper with query parameters if the helper parses and trusts payload parameters (such as expiration timestamps) before validating the cryptographic signature of the URI.
Auth Bypass: Signing relative URI paths instead of absolute URLs allows signature reuse or tampering across different hostnames, which could lead to unauthorized email validation on unintended domains.
