Descriptions

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.

Esto puede resultar en un error fatal, y potencialmente ocurrir un fallo en bloquear o restringir a un usuario potencialmente nefasto
