Descriptions

Mattermost versions 9.8.x <= 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2 and 9.5.x <= 9.5.5, when shared channels are enabled, fail to use constant time comparison for remote cluster tokens which allows an attacker to retrieve the remote cluster token via a timing attack during remote cluster token comparison.

Las versiones de Mattermost 9.8.x &lt;= 9.8.0, 9.7.x &lt;= 9.7.4, 9.6.x &lt;= 9.6.2 y 9.5.x &lt;= 9.5.5, cuando los canales compartidos están habilitados, no pueden usar la comparación de tiempo constante para tokens de clúster remoto, lo que permite a un atacante recuperar el token de clúster remoto mediante un ataque de sincronización durante la comparación de tokens de clúster remoto.
