CVE-2025-0672: WSO2 Identity Server

Low severity, CVSS 3.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• WSO2 Identity Server: version 5.10.0 only; version 5.11.0 only
• WSO2 Identity Server As Key Manager: version 5.10.0 only
• WSO2 Open Banking Iam: version 2.0.0 only
