CVE-2026-46508: CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') in vercel turborepo
CVE-2026-46508 is a command injection vulnerability in the Vercel Turborepo LSP VS Code extension prior to version 2. 9. 14000. The extension executes shell commands derived from workspace-controlled values without proper neutralization, allowing a malicious workspace to inject arbitrary commands. This can lead to arbitrary command execution with the privileges of the local VS Code process when the extension activates or a task is run. The vulnerability has a high severity score of 8. 4 and is fixed in version 2. 9. 14000.
AI Analysis
Technical Summary
The Turborepo LSP VS Code extension versions before 2.9.14000 use string-based shell command execution for daemon commands and task runs, interpolating workspace-controlled values such as workspace settings or task names directly into shell commands. This improper neutralization of special elements (CWE-77) enables a malicious workspace to craft values that, when interpreted by the shell, execute arbitrary commands with the local VS Code process privileges. The vulnerability is addressed by updating the extension to version 2.9.14000.
Potential Impact
Successful exploitation allows arbitrary command execution on the user's machine with the privileges of the VS Code process, potentially leading to unauthorized actions or compromise of the local environment. The vulnerability requires user interaction (UI:A) and local access (AV:L) but does not require privileges or authentication. The impact is rated high with a CVSS 4.0 score of 8.4.
Mitigation Recommendations
Upgrade the Turborepo LSP VS Code extension to version 2.9.14000 or later, where this command injection vulnerability is fixed. No other mitigation or temporary workaround is indicated. Users should avoid opening untrusted workspaces until patched.
