Title: MediaWiki Other Vulnerability
Overview:

An issue was discovered in the AbuseFilter extension in MediaWiki through 1.36. If the MediaWiki:Abusefilter-blocker message is invalid within the content language the filter user falls back to the English version but that English version could also be invalid on a wiki. This would result in a fatal error and potentially fail to block or restrict a potentially nefarious user.
