Visual Studio Code: Security feature bypass in rendered UI layers
Summary
Visual Studio Code versions from 1.0.0 before 1.145.3 contain a security feature bypass caused by improper restriction of rendered UI layers or frames (CWE-1021). A local attacker can bypass a security feature, which Microsoft rates with high impact on confidentiality, integrity and availability. Exploitation requires that a user interacts with attacker-controlled content, for example a malicious project, web page or extension.
Affected
- Microsoft Visual Studio Code from 1.0.0 before 1.145.3\n- CVSS 3.1: 8.6 (High), AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Fixed in
- Update to Visual Studio Code 1.145.3 or later
Workaround
- Unknown. No vendor-documented workaround found. Patching is the recommended fix.
Exploitation
- No evidence of exploitation in the wild found at the time of writing.\n- Not listed in the CISA KEV catalogue.\n- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Inventory all Visual Studio Code installations, including developer and remote machines.\n- Update to version 1.145.3 or later and verify with 'code --version'.\n- Restrict use to trusted workspaces and extensions until patched.\n- Check the MSRC advisory for official fix details before closing the ticket.
