MEDIUM 6.1EPSS 1.12%

Does this matter?

Lower severity and a low EPSS score (1.12%). Track it; it rarely justifies an emergency change on its own.

Description

The Cosmos Skin for MediaWiki through 1.35.0 has stored XSS because MediaWiki messages were not being properly escaped. This is related to wfMessage and Html::rawElement, as demonstrated by CosmosSocialProfile::getUserGroups.
