Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The user provider was vulnerable to a critical authentication bypass where a null social ID returned by an OAuth provider allowed users to login as other registered accounts, compounded by refreshUser returning stale or unrefreshed user entities.
Auth Bypass: The authentication provider bypassed post-authentication checks (allowing locked/disabled accounts to log in) and suffered from token expiration issues because expired tokens were recycled without forcing a refresh.
Authentication Bypass: Expired tokens remained active because isExpired() always evaluated to false, exacerbated by missing parent constructor initialization and failure to preserve serialization states.
