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.
