How We Found Thousands of Exposed NVIDIA GPUs and a Way to Disrupt Them (CVE-2026-47483)

Reddit •/u/Pale_Fly_2673 • October 8, 2026

TL;DR: NVIDIA DCGM Exporter is a widely used monitoring tool that collects GPU metrics like utilization, memory, temperature, and power consumption from AI servers. We discovered that thousands of these monitoring endpoints are exposed to the public internet, allowing anyone to inspect GPU infrastructure. Worse, we found a high-severity vulnerability (CVE-2026-47483, CVSS 8.2) that lets unauthenticated attackers exhaust server resources, crash GPU monitoring, and potentially disrupt AI workloads remotely. A few other interesting findings: 2,100+ exposed GPU servers , revealing telemetry from 12,000+ GPUs worth ~$100M , including H100s, H200s, and Blackwell GPUs. 60% of exposed GPUs reported 0% utilization across our scans. 12,096 additional servers exposed infrastructure details, including OS, firmware, and networking information. NVIDIA fixed the vulnerability following our responsible disclosure. Full research: submitted by /u/Pale_Fly_2673 [link] [ ]
