Description Guilherme de Almeida Suckevicz 2021-04-06 16:52:22 UTC 
An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. On Special:NewFiles, all the mediastatistics-header-* messages are output in HTML unescaped, leading to XSS.

Statement:

The mediawiki package was removed from OpenShift Container Platform (OCP) in version 4.3, therefore for OCP 4 has been marked as out of support scope.
