- CWE-639 - Authorization Bypass Through User-Controlled Key
Summary
A flaw was found in the multicloud-operators-channel component. This vulnerability allows a user with specific permissions to manipulate how the system handles sensitive information, known as Secrets, across different parts of the system (namespaces). By exploiting this, an attacker can modify these Secrets in unauthorized areas. This could lead to unauthorized access to information or elevated privileges within the system.
