Recurring patterns

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

Open Redirect: Inadequate URL normalization and parsing allowed attackers to bypass protocol-relative URL checks using embedded control characters (such as ASCII tabs, CR, and LF) or double-slash prefixes, leading to arbitrary redirection via the Location header.

Timing Attack: The use of a custom string comparison function for signed cookie verification was susceptible to timing attacks, which could allow attackers to forge valid cookie signatures.
