CVE-2025-0672

Authentication Bypass in Multiple WSO2 Products via Stale FIDO Credential Association

State: Published
Severity: 3.3 Low
Published: Sep 23, 2025
Updated: Sep 25, 2025
Reserved: Jan 23, 2025

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.
