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

An attacker with authenticated access to VICIdial as an "agent" can execute arbitrary shell commands as the "root" user. This attack can be chained with CVE-2024-8503 to execute arbitrary shell commands starting from an unauthenticated perspective.
