Description
Semantic MediaWiki 7.3.1 before 7.4.1 contains an incorrect authorization vulnerability in EditProtectionUpdater::userMayChangeProtection() that checks protection changes against the page's latest revision author. Editors can add {{#set:Is edit protected=false}} to a transcluded template, removing administrator edit and move protection logged under the administrator's name.
