Description Guilherme de Almeida Suckevicz 2021-04-06 17:07:50 UTC 
An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Blocked users are unable to use Special:ResetTokens. This has security relevance because a blocked user might have accidentally shared a token, or might know that a token has been compromised, and yet is not able to block any potential future use of the token by an unauthorized party.

The mediawiki package was removed from OpenShift Container Platform (OCP) in version 4.3, therefore for OCP 4 has been marked as out of support scope.
