CVE-2026-70334

Workspace Trust bypass via nested settings

Published Sep 8, 2026 · Updated Sep 9, 2026

Workspace Trust bypass in Microsoft Visual Studio Code before 1.136.2 allows local users to apply restricted workspace settings. The Workspace Trust filter checks each raw top-level JSON key against the configuration registry, but it does not resolve nested objects to their equivalent dotted setting paths. Exploitation requires a user to open an attacker-crafted workspace in Restricted Mode; the applied settings can execute commands or code with the user's permissions.
