Recurring patterns

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

Cross-Site Request Forgery (CSRF): Failure to enforce the anti-CSRF 'state' parameter during OAuth2 flows allows attackers to perform login CSRF, binding an attacker's account credentials to a victim's session. This risk is present across multiple provider-specific implementations.

Deserialization: Unsafe deserialization of stored OAuth states via PHP's unserialize() allows authenticated attackers or anyone who can manipulate the Redis store to trigger PHP Object Injection, potentially leading to arbitrary code execution.

Auth Bypass: Misalignment between signature generation parameters and the generated Authorization header in OAuth1 can lead to authentication bypass or protocol validation failures due to incomplete parameter validation.
