Semantic MediaWiki 3.0.0 before 7.3.0 Missing Authorization via smwtask API

Check your stack

The advisory, in context

Semantic MediaWiki from 3.0.0 before 7.3.0 contains a missing authorization vulnerability in the api.php smwtask module that allows unauthenticated attackers to run admin-only maintenance tasks. Attackers can use the public anonymous CSRF token to read internal store statistics, enqueue jobs like smw.entityIdDisposer, and execute queued jobs, degrading performance and altering semantic data.

Affected packages

This source has no supported package-version data for matching. You can read the advisory here, but this record alone cannot power a dependency check.

Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
