NVD Description

Note: Versions mentioned in the description apply only to the upstream mediawiki package and not the mediawiki package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

An issue was discovered in the OATHAuth extension in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. For Wikis using OATHAuth on a farm/cluster (such as via CentralAuth), rate limiting of OATH tokens is only done on a single site level. Thus, multiple requests can be made across many wikis/sites concurrently.
