Free first check from your website. Connect your repo for the full answer.
Wikis running Semantic MediaWiki from 4.2.0 up to but not including 7.4.1 that grant the smw-schemaedit right to users. Wikis without that right assigned to untrusted accounts have a much smaller exposure, and wikis on managed hosting should check with the host.
Not affected if smw-schemaedit-not-granted, version-7.4.1-or-later
