No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In multiple locations, there is a possible way to execute code in the launcher process due to an over-privileged shell user. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
