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 allows users deactivated through users.deactivateIdle to keep using already-issued login tokens. A user that an administrator has marked inactive for idleness can still access authenticated REST endpoints with the old 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.
