Wso2 Carbon Magiclink Authenticator Module

The system accepts authentication requests without sufficient validation to enforce tenant isolation when using Email OTP, SMS OTP, or Magic Link as first-factor authenticators. This failure to adequately separate user data between tenants can lead to the exposure of personally identifiable information. Successful exploitation allows an attacker to disclose personally identifiable information of users in different tenants, resulting in privacy violations and potential regulatory non-compliance. This may include unauthorized access to user details such as mobile numbers.

Due to a lack of user account state validation during authentication, locked user accounts can be successfully authenticated using Magic Link or Pass Key methods. This bypasses the intended security control that should prevent access to accounts that have been locked. This vulnerability may allow unauthorized access to applications and sensitive data associated with accounts that should have been restricted via the account lock mechanism. It also undermines the effectiveness of the account lock mechanism intended to prevent further login attempts.

The Magic Link authentication flow accepts multiple invalid authentication requests without adequate rate limiting or resource control, leading to uncontrolled memory usage growth. This vulnerability can result in a denial-of-service condition, causing service unavailability for deployments that utilize the Magic Link authenticator. The impact is limited to these specific deployments and requires repeated invalid authentication attempts to trigger.
