Description
The Velocity template engine, utilized by the affected product, accepts and processes template syntax without sufficient sanitization or validation of user-controlled input. This allows an authenticated administrator to inject arbitrary template syntax. Successful exploitation enables an attacker with administrative privileges to execute arbitrary template code on the server. This can lead to significant security consequences, including remote code execution, manipulation of data, and unauthorized access to sensitive information.
