CVE-2025-12624Improper Token Invalidation in WSO2 Identity Server Allows Access After Account Lock
Medium 6.0
In plain English
A medium-severity security flaw in WSO2 Identity Server from WSO2. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 7% of all known vulnerabilities).
Official description
Active access tokens are not revoked or invalidated when a user account is locked within WSO2 Identity Server. This failure to enforce revocation allows previously issued, valid tokens to remain usable, enabling continued access to protected resources by locked user accounts. The security consequence is that a locked user account can maintain access to protected resources through the use of existing, unexpired access tokens. This creates a security gap where access control policies are bypassed, potentially leading to unauthorized data access or actions until the tokens naturally expire.
