CVE-2018-9243
GitLab Community and Enterprise Editions version 8.4 up to 10.4 are vulnerable to XSS because a lack of input validation in the merge request component leads to cross site scripting (specifically, filenames in changes tabs of merge requests).
Does this matter?
Lower severity and a low EPSS score (0.98%). Track it; it rarely justifies an emergency change on its own.
