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.
