Summary

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.

Remediation

1. Inventory every Semantic-mediawiki Semantic Mediawiki deployment, including staging.
2. Upgrade Semantic-mediawiki Semantic Mediawiki to 7.3.0.
3. Confirm the running version after the upgrade.
