| Description | Due to the use of a vulnerable third-party Velocity template engine, a malicious actor with admin privilege may inject and execute arbitrary template syntax within server-side templates. Successful exploitation of this vulnerability could allow a malicious actor with admin privilege to inject and execute arbitrary template code on the server, potentially leading to remote code execution, data manipulation, or unauthorized access to sensitive information. | 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. |
