Description

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

 - In BookStack greater than or equal to 0.18.0 and less than 0.29.2, there is an XSS vulnerability in
 comment creation. A user with permission to create comments could POST HTML directly to the system to be
 saved in a comment, which would then be executed/displayed to others users viewing the comment. Through

 most impacts scenarios where not-trusted users are given permission to create comments. This has been
 fixed in 0.29.2. (CVE-2020-11055)
