Semantic MediaWiki 2.5.0 before 7.3.1 Missing Authorization via Is edit protected

Summary

Semantic MediaWiki from 2.5.0 before 7.3.1 contains an improper authorization vulnerability that allows ordinary editors to permanently protect pages by adding an Is edit protected annotation. When $smwgEditProtectionRight is enabled, EditProtectionUpdater applies indefinite edit and move restrictions without checking the author's rights, locking other editors and administrators out.

Remediation

1. Inventory every SemanticMediaWiki SemanticMediaWiki deployment, including staging.
2. Upgrade SemanticMediaWiki SemanticMediaWiki to 7.3.1.
3. Confirm the running version after the upgrade.
