SCA: security update for shescape (GHSA-44vr-rwwj-p88h)

critical Tenable Self-Hosted Container Security Plugin ID 409944

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Shescape is a simple shell escape package for JavaScript. Affected versions were found to have
 insufficient escaping of white space when interpolating output. This issue only impacts users that use the
 `escape` or `escapeAll` functions with the `interpolation` option set to `true`. The result is that if an
 attacker is able to include whitespace in their input they can: 1. Invoke shell-specific behaviour through
 shell-specific special characters inserted directly after whitespace. 2. Invoke shell-specific behaviour
 through shell-specific special characters inserted or appearing after line terminating characters. 3.
 Invoke arbitrary commands by inserting a line feed character. 4. Invoke arbitrary commands by inserting a
 carriage return character. Behaviour number 1 has been patched in [v1.5.7] which you can upgrade to now.
 No further changes are required. Behaviour number 2, 3, and 4 have been patched in [v1.5.8] which you can
 upgrade to now. No further changes are required. The best workaround is to avoid having to use the
 `interpolation: true` option - in most cases using an alternative is possible, see [the
 recipes](https://github.com/ericcornelissen/shescape#recipes) for recommendations. Alternatively, users
 may strip all whitespace from user input. Note that this is error prone, for example: for PowerShell this
 requires stripping `'\u0085'` which is not included in JavaScript's definition of `\s` for Regular
 Expressions. (CVE-2022-31180)
