CVE-2024-8995Authorization Code issued for Deleted User reuse in Multiple WSO2 Products Allows Unauthorized Access
Medium 4.9
In plain English
A medium-severity security flaw in WSO2 API Control Plane 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 8% of all known vulnerabilities).
Official description
Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused. If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead to unauthorized access to sensitive resources and services, contingent on the scopes originally authorized for the compromised authorization code.
