CVE-2017-8808
MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 has XSS when the $wgShowExceptionDetails setting is false and the browser sends non-standard URL escaping.
Does this matter?
Lower severity and a low EPSS score (1.04%). Track it; it rarely justifies an emergency change on its own.
