Critical CVSS 9.4

CVE-2026-66147

NVD analysis in progress

An unauthenticated command injection vulnerability was identified in the GMS Dispatcher Service in GMS 9.5.1 and earlier versions which allows remote attacker to perform remote code execution through specially crafted requests.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim.
Impact
An attacker can read some data, modify or destroy data and take the service offline.
Weakness
The application interprets attacker-supplied code, which then runs with its privileges.
Likelihood
Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.

What to doPatch without waiting for the next scheduled cycle. Start with the instances exposed to the internet.
