CVE-2018-19570
GitLab CE/EE, versions 11.3 before 11.3.11, 11.4 before 11.4.8, and 11.5 before 11.5.1, are vulnerable to an XSS vulnerability in Markdown fields via unrecognized HTML tags.
Does this matter?
Lower severity and a low EPSS score (0.98%). Track it; it rarely justifies an emergency change on its own.
