Description
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.

• mediawiki mediawiki (< 1.31.10)
• mediawiki mediawiki (>= 1.32.0 < 1.34.4)
• fedoraproject fedora 33
