CVE-2020-12051 (GCVE-0-2020-12051)

Vulnerability from cvelistv5 – Published: 2020-04-21 21:24 – Updated: 2024-08-04 11:48

Summary

The CentralAuth extension through REL1_34 for MediaWiki allows remote attackers to obtain sensitive hidden account information via an api.php?action=query&meta=globaluserinfo&guiuser= request. In other words, the information can be retrieved via the action API even though access would be denied when simply visiting wiki/Special:CentralAuth in a web browser.
