Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: DingTalk provider failed to validate that essential identification fields like open_id were present and non-empty in the OAuth response, potentially leading to unauthorized user access.
Auth Bypass: WeChat provider did not explicitly throw an authorization exception when openid or access_token was missing in the provider's response, causing unhandled array-key exceptions and potentially allowing invalid OAuth payloads to bypass authentication checks.
