Visual Studio

CVE-2026-41109 describes an improper neutralization of special elements in output used by a downstream component ('injection') vulnerability in GitHub Copilot and Visual Studio, allowing an unauthorized attacker to bypass a security feature over a network.

The analytic identifies instances where wmiprvse.exe spawns msbuild.exe, an unusual process relationship indicative of potential COM object misuse and unauthorized code execution on Windows systems.

The execution of Microsoft devtunnels.exe can be abused by attackers to expose compromised systems to the internet, establish covert communication channels, and bypass network security measures, facilitating data exfiltration or command-and-control.

Adversaries may create scheduled tasks on Windows systems to establish persistence, move laterally, or escalate privileges, and this detection identifies such activity by monitoring Windows event logs for scheduled task creation events, excluding known benign tasks and those created by system accounts.

This detection identifies potential misuse of Microsoft Devtunnels within Visual Studio by detecting image load events, indicating that an attacker could expose a compromised system or service to the internet for covert communication and data exfiltration.
