Descriptions

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.

Se detectó un problema en MediaWiki versiones anteriores a 1.31.12 y versiones 1.32.x hasta 1.35.x anteriores a 1.35.2. Los usuarios bloqueados no pueden usar Special:ResetTokens. Esto presenta relevancia para la seguridad porque un usuario bloqueado podría haber compartido accidentalmente un token, o podría saber que un token ha sido comprometido y, sin embargo, no puede bloquear ningún uso futuro potencial del token por una parte no autorizada
