Name of the Vulnerable Software and Affected Versions MediaWiki versions prior to 1.33.1

Description The issue is related to the Special:Redirect function in MediaWiki, which allows information disclosure of suppressed usernames via a User ID Lookup. This is due to a lack of protection for internal data. An attacker can exploit this to gain unauthorized access to protected information by searching for user IDs.

Recommendations For MediaWiki versions prior to 1.33.1, update to version 1.33.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the Special:Redirect function until a patch is available. Avoid using the User ID Lookup feature in the affected Special:Redirect function until the issue is resolved.
