Description

Semantic MediaWiki from 7.3.0 before 7.3.1 contains a missing authorization vulnerability in the smwtask update task that allows users with edit rights to force semantic updates on arbitrary pages. Attackers can supply a serialized subject parameter for a restricted page to trigger forced reparsing, semantic-store writes, and resource-intensive dependency work.
