How to fix?

Overview

mediawiki/core is a Free software wiki application developed by the Wikimedia Foundation and others.

Note: This package is not maintained on Packagist anymore, but newer releases exist.

Affected versions of this package are vulnerable to Access Restriction Bypass via the OATHAuth extension. For Wikis using OATHAuth on a farm/cluster, rate limiting of OATH tokens is only done on a single site level. Thus, multiple requests can be made across many wikis/sites concurrently.
