Exposure of home directory through shescape on Unix with Bash
Summary
Exposure of home directory through shescape on Unix with Bash
Original description
The description as published by the source.
Shescape is a shell escape package for JavaScript. An issue in versions 1.4.0 to 1.5.1 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. Depending on how the output of shescape is used, directory traversal may be possible in the application using shescape. The issue was patched in version 1.5.1. As a workaround, manually escape all instances of the tilde character (~) using arg.replace(/~/g, "\\~").
