Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incomplete verification logic or caching placeholders instead of actual validation timestamps can allow attackers to perform replay attacks, reusing the same One-Time Password (OTP) within valid time windows. This is further documented under CVE-2022-25838.
Authentication Bypass: A lack of strict type validation on password inputs during confirmation requests allows PHP type-juggling or array-based payloads to bypass password verification screens entirely.
Auth Bypass: Failing to completely nullify/invalidate 2FA confirmation timestamps when disabling two-factor authentication leaves stale states that can be exploited to bypass confirmation checks upon re-enabling the feature.
