Upgrade shescape to version 2.1.14, 3.0.1 or higher.
Overview
shescape is a simple shell escape library
Affected versions of this package are vulnerable to Command Injection via the getEscapeFunction function when using the escape or escapeAll APIs on Windows with shell set to cmd.exe, or with shell set to true when CMD is the default. An attacker can execute arbitrary commands by supplying specially crafted arguments that break out of a parenthesized CMD construct and inject shell syntax.
