CVE-2025-64660
📋 TL;DR
This vulnerability allows an authorized attacker to execute arbitrary code remotely on systems running vulnerable versions of GitHub Copilot and Visual Studio Code. Attackers can exploit improper access controls to run malicious code over network connections. Users of affected software versions are at risk.
💻 Affected Systems
- GitHub Copilot
- Visual Studio Code
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to install malware, steal sensitive data, pivot to other systems, and maintain persistent access.
Likely Case
Attacker gains code execution within the IDE context, potentially accessing project files, credentials, and executing malicious commands.
If Mitigated
Limited impact with proper network segmentation, least privilege access, and security controls in place.
🎯 Exploit Status
Requires authorized access but network-based execution lowers barrier.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Microsoft Security Advisory for specific versions
Vendor Advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-64660
Restart Required: Yes
Instructions:
1. Open Visual Studio Code
2. Go to Help > Check for Updates
3. Install available updates
4. Restart Visual Studio Code
5. For GitHub Copilot, ensure extension is updated to latest version
🔧 Temporary Workarounds
Disable Network Features
allDisable network connectivity features in VS Code to prevent remote exploitation
Set 'remote.SSH.enable' to false in settings.json
Disable Live Share and other collaboration features
Network Segmentation
allRestrict network access to development systems
Configure firewall to block inbound connections to VS Code ports
Use network policies to isolate development environments
🧯 If You Can't Patch
- Isolate affected systems from production networks and internet
- Implement strict access controls and monitor for suspicious network activity
🔍 How to Verify
Check if Vulnerable:
Check VS Code version and compare against patched versions in Microsoft advisory
Check Version:
code --version
Verify Fix Applied:
Verify VS Code version is updated to patched version and restart application
📡 Detection & Monitoring
Log Indicators:
- Unusual network connections from VS Code process
- Suspicious process execution originating from code.exe or VS Code
Network Indicators:
- Unexpected outbound connections from development systems
- Anomalous network traffic patterns from IDE applications
SIEM Query:
process_name:code.exe AND (network_connection:true OR process_execution:unusual)
