Microsoft Visual Studio Code: Security feature bypass through UI misrepresentation
Summary
Visual Studio Code versions from 1.0.0 before 1.145.3 contain a user interface misrepresentation of critical information. An unauthorized remote attacker can use it to bypass a security feature. The attack requires user interaction. The research notes link this CVE to a GitHub issue about malicious MCP installation links, but this mapping is not confirmed.
Affected
- Microsoft Visual Studio Code 1.0.0 to before 1.145.3
Fixed in
- Visual Studio Code 1.145.3 or later
Workaround
- Unknown for the CVE itself. Until patching, do not open untrusted vscode:mcp/install links and review the displayed server configuration before approving an installation.
Exploitation
- No evidence of exploitation in the wild found. CISA SSVC: exploitation none, automatable no, technical impact total.
- No public proof of concept found.
- Not listed as known exploited (KEV: No, per third-party tracker).
Our recommendation
- Update Visual Studio Code to 1.145.3 or later on all endpoints, or through the managed deployment.
- Check the installed build on developer and staff workstations.
- Train staff not to approve unexpected MCP installation links.
- Monitor the MSRC advisory and NVD for updates on the analysis and the mapping.
