Recurring patterns

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

Auth Bypass: A critical flaw in Next.js router integration and middleware permitted unauthorized users to bypass key authentication checks and escalate privileges. This is documented under CVE-2024-22206 and addressed in changes like ecb60da48029b9cb2d17ab9b0a73cb92bc5c924b.

Auth Bypass: A critical logic inversion during the removal of the svix dependency caused the webhook verification mechanism to accept invalid signatures and reject valid ones, creating a complete validation bypass.

Open Redirect: Insecure handling of redirect URLs allowed attackers to inject javascript: or other dangerous protocol schemes, leading to cross-site scripting (XSS) or arbitrary destination redirects.
