CVE-2024-49050Network attack vector

Code execution via untrusted workspace interpreter discovery

Published Nov 12, 2024 · Updated Jul 8, 2025

Trust boundary violation in Microsoft's Python extension for Visual Studio Code before 2024.18.2 allows remote attackers to execute code. The getNativePythonFinder path starts Python Environment Tools discovery without checking workspace trust, allowing a repository-supplied Python executable to run. Exploitation requires opening a specially crafted untrusted workspace, after which code executes in the Visual Studio Code user's context.
