NVD Description

Note: Versions mentioned in the description apply only to the upstream gitlab package and not the gitlab package as distributed by Debian.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows XSS (issue 1 of 2). Markdown fields contain a lack of input validation and output encoding when processing KaTeX that results in a persistent XSS.
