The issue allows for exposure of the home directory on Unix systems when using Bash with the escape or escapeAll functions from the shescape API with the interpolation option set to true. Other tested shells, Dash and Zsh, are not affected.
const cp = require("child_process");
const shescape = require("shescape");
const payload = "home_directory=~";
const options = { interpolation: true };
console.log(cp.execSync(`echo ${shescape.escape(payload, options)}`));
// home_directory=/home/user
Depending on how the output of shescape is used, directory traversal may be possible in the application using shescape.
The issue was patched in v1.5.1.
Manually escape all instances of the tilde character (~) using arg.replace(/~/g, "\\~").
