CVE-2025-62453
📋 TL;DR
This vulnerability allows an authorized attacker to bypass local security features in GitHub Copilot and Visual Studio Code by exploiting improper validation of generative AI output. It affects users of these Microsoft development tools who have local access to the system. The attacker must already have authorized access to the targeted environment.
💻 Affected Systems
- GitHub Copilot
- Visual Studio Code
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authorized user could bypass security controls to execute unauthorized code or access restricted resources within the local development environment.
Likely Case
An authorized developer could bypass security features to access or modify code they shouldn't have access to within their local development workspace.
If Mitigated
With proper access controls and monitoring, the impact is limited to potential policy violations within the local development environment.
🎯 Exploit Status
Exploitation requires authorized access and understanding of how to manipulate generative AI output to bypass security features.
