Users should monitor the vendor's communications for updates. Until a fix is released, avoid exposing the vulnerable component to untrusted users or inputs that could manipulate the 'template' argument. Consider implementing web application firewalls or input sanitization as temporary mitigations.
Description

The vulnerability has a low CVSS score of 2.4 and requires high privileges and user interaction for exploitation.
