CVE-2026-48122

Code execution via workspace-controlled startup paths

Published Aug 7, 2026 · Updated Aug 7, 2026

OS command injection in Shopify Ruby LSP VS Code extension before 0.10.4 allows attackers to execute code through workspace settings. Its startup logic accepts repository-controlled executable, version-manager, and Gemfile paths; one value reaches a shell subprocess without neutralization. Exploitation requires a developer to open and trust the malicious workspace, after which code runs with that developer's privileges.
