CVE-2026-116873

Semantic MediaWiki from 7.3.0 before 7.3.1 contains a missing authorization vulnerability in the smwtask API module that allows unauthenticated attackers to run queued jobs and force store updates. Attackers can use the public anonymous CSRF token with run-joblist to execute arbitrary job types in unbounded counts, or invoke update on sysop-protected pages, leaking page titles and exhausting resources.
