Playing It SFAPE: Code Execution in Isolated User Mode

Doyensec discovered multiple vulnerabilities in SFAPE.dll, a VBS enclave shipped with Windows, and chained them to gain code execution within the enclave in Windows Isolated User Mode (VTL1). The post explores how VBS enclaves work and how memory corruption can undermine their isolation guarantees. Microsoft addressed the reported issue in the September 2026 bulletin under CVE-2026-83498.

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

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.

I found yet another way to invoke JavaScript functions without parentheses

It turns out you can overwrite the Error.prepareStackTrace method with the function constructor. Then, using prototype pollution, you can inject valid JavaScript code to generate arbitrary functions and invoke it using the usual tricks.
