Descriptions

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, "\\~")`.

Shescape es un paquete de escape de shell para JavaScript. Un problema en las versiones 1.4.0 a 1.5.1 permite una exposición del directorio de inicio en los sistemas Unix cuando es usada Bash con las funciones "escape" o "escapeAll' de la API _shescape_ con la opción "interpolation" establecida en "true". Otros shells probados, Dash y Zsh, no están afectados. Dependiendo de cómo es usada la salida de _shescape_, puede ser posible un salto de directorio en la aplicación que usa _shescape_. El problema fue parcheado en la versión 1.5.1. Como medida de mitigación, escape manualmente todas las instancias del carácter tilde ("~") usando "arg.replace(/~/g, "\~~")`
