Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Allowing users to authenticate via Sign-In with Ethereum (SIWE) using arbitrary emails instead of validating specific provider credentials allowed complete identity spoofing and account takeover.

SSRF: The image proxy endpoint was susceptible to Server-Side Request Forgery (SSRF) via open redirects and missed private IPv6 range exclusions, potentially exposing sensitive internal systems.

Auth Bypass: Endpoint registration lacked strict verification against declared OpenAPI specifications, enabling the registration of arbitrary and unauthorized external endpoints.
