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

Multiple security issues were found in MediaWiki, a website engine for collaborative work, which could result in incomplete page/blocking protection, denial of service or cross-site scripting.
