Attackers can exploit this by injecting JavaScript payloads via the uselang=x-xss language override, which causes crafted message keys to be rendered unescaped.\n\n\n\n\nThis issue affects Mediawiki - ApprovedRevs extension: from 1.39.X before 1.39.13, from 1.42.X before 1.42.7, from 1.43.X before 1.43.2.",
