What is CVE-2025-0672?

An authentication bypass flaw exists in various WSO2 products with FIDO authentication enabled. When a user account is deleted, its FIDO registration data remains, potentially allowing a new account with the same username to associate with this data. If the deleted user attempts to access the system, they can authenticate using their former FIDO credentials, thereby impersonating the new user account. This vulnerability poses significant security risks for deployments utilizing FIDO authentication.
