### Summary On Windows, builds a PowerShell command using the value passed to . The default sanitizer removes ASCII quotes but keeps Unicode curly quotes, spaces, and parentheses. A crafted service name can use those characters to break out of the generated filter string and run a PowerShell expression. The expression runs with the permissions of the Node.js process. This report confirms version . Other package versions have not been checked. ### Details In , sanitizes the caller's string with and later inserts each resulting name into a command. The Windows branch passes that command to . The sanitizer in removes the ASCII double quote, but it does not remove U+201C or U+201D, the left and right curly double quotation marks. It also permits spaces and parentheses when called in its default, non-strict mode. PowerShell accepts the curly marks as string delimiters, so an input can end the filter string and place a command expression in the generated command. For example, the input below uses curly quotation marks to end the generated filter string and execute . I reproduced this call on Windows against the checked-out source; it created a marker file with the Node.js process account. ### Proof of concept Run this on Windows in a disposable directory with Node.js and PowerShell available: Save the following as , then run : Expected output: The Windows run returned an array and created the marker ( ). A benign input left the marker absent. The script removes the marker afterward. I did not identify an application network route that forwards remote input to , so remote exploitability depends on the consuming application. ### Impact An application that passes attacker-controlled input to on Windows can execute PowerShell commands with the Node.js process account's permissions. Depending on that account, commands may read or change accessible files, alter application data, or disrupt the service. I searched this repository for HTTP servers, route handlers, and listener ca
