Prior to 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8, and 7.10.12, Rocket.Chat does not revoke OAuth bearer or refresh tokens when a user is deactivated. A deactivated user can continue using an existing OAuth access token, and can also mint a fresh access token from an existing refresh token. This vulnerability is fixed in 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8, and 7.10.12."

Antes de 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8 y 7.10.12, Rocket.Chat no revoca los tokens portadores de OAuth o de actualización cuando un usuario es desactivado. Un usuario desactivado puede continuar usando un token de acceso OAuth existente, y también puede generar un nuevo token de acceso a partir de un token de actualización existente. Esta vulnerabilidad está corregida en 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8 y 7.10.12."
