Description
Semantic MediaWiki from 3.0.0 before 7.3.1 contains a cross-site request forgery vulnerability in Special:SMWAdmin because it overwrites the wpEditToken with a freshly generated valid token. Attackers can lure an authenticated smw-admin user to a malicious page that triggers schema setup, entity-disposal, or job actions, causing semantic data loss and resource exhaustion.
