Recurring patterns

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

Open Redirect: Unvalidated redirect paths extracted directly from URL parameters allow attackers to construct highly convincing phishing vectors by redirecting users to arbitrary external domains. Migrating these operations to secure client-side storage is critical.
Auth Bypass: Flaws in serializing, verifying, and caching the user's active session state can lead to local cache poisoning or bypassing authentication checks if invalid or unverified credentials are erroneously stored.
Cryptographic Weakness: Incorrect formatting transformations (such as missing hex prefixes during HMAC step conversions) undermine hash verification strength, rendering signed components untrustworthy.
