Visual Studio Code: Server-side request forgery with security feature bypass
Summary
A server-side request forgery (SSRF) flaw in Microsoft Visual Studio Code allows an unauthorized attacker to bypass a security feature over the network. The CVSS score is 8.8, and the CNA rates the impact on confidentiality, integrity and availability as high. Exploitation requires user interaction (UI:R), so an attacker would need a user to process attacker-controlled content. The attack path is not described in the available sources.
Affected
- Microsoft Visual Studio Code from 1.0.0 before 1.145.3
Fixed in
- Fixed in 1.145.3 according to the CVE record. This version could not yet be confirmed against release notes or the MSRC advisory.
Workaround
- Unknown. No vendor-documented workaround was found.
- Not confirmed as a fix for this CVE: from VS Code 1.126, new folders open in Restricted Mode by default.
Exploitation
- Exploit maturity is recorded as Unproven (E:U) in the CVSS vector.
- One aggregator lists the CVE as not in the CISA KEV catalog; no CISA entry was found directly.
- No public proof of concept is known as of publication.
Our recommendation
- Inventory all VS Code installations, including user-scope installs on developer workstations, and record their versions.
- Check the MSRC advisory and the VS Code update page for the fixed build, and update once 1.145.3 is confirmed as available.
- Until patched, keep Restricted Mode enabled for untrusted folders and avoid opening untrusted repositories.
- Re-check NVD and the MSRC page in a few days, as the record was published recently.
