No affected components available
Summary
The Lobster extension tool execution path used a Windows shell fallback (shell: true) after spawn failures (EINVAL/ENOENT). In that fallback path, shell metacharacters in command arguments can be interpreted by the shell, enabling command injection.

2026.2.19
Technical Details
In affected releases (including v2026.2.17), extensions/lobster/src/lobster-tool.ts retried subprocess launch with shell: true on Windows for EINVAL/ENOENT spawn errors. The fix removes shell fallback and resolves Windows wrappers to explicit executable/script argv execution.
