NVD description
Semantic MediaWiki 2.5.0 before 7.4.1 contains a missing authorization vulnerability that allows editors without the edit-protection right to lock pages by adding an Is edit protected annotation. Attackers can add [[Is edit protected::true]] to pages or #set it in widely transcluded templates, so the TitleQuickPermissions hook blocks other editors and administrators from editing, moving or deleting them indefinitely.
