Stored XSS in Wikimedia Foundation WikibaseMediaInfo 1.39 through 1.43 allows remote authenticated users to inject script into file pages. WikibaseMediaInfo dangerously serializes attacker-controlled wikitext into file-page content without neutralizing executable markup. Exploitation requires a low-privileged account and a user to view the crafted file page, where the script runs in that viewer's browser context.
