What is CVE-2025-0672?
CVE-2025-0672 is a low-severity authentication bypass vulnerability in Wso2 Identity Server, published on 23 Sep 2025. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
An authentication bypass vulnerability exists in multiple WSO2 products when FIDO authentication is enabled. When a user account is deleted, the system does not automatically remove associated FIDO registration data. If a new user account is later created using the same username, the system may associate the new account with the previously registered FIDO device.
This flaw may allow a previously deleted user to authenticate using their FIDO credentials and impersonate the newly created user, resulting in unauthorized access. The vulnerability applies only to deployments that utilize FIDO-based authentication.
