Description

Semantic MediaWiki versions from 7.3.0 up to but not including 7.3.1 have a missing authorization vulnerability in the smwtask update task. This flaw allows users with edit rights to force semantic updates on arbitrary pages, potentially causing resource-intensive operations and unauthorized semantic-store writes.
