CVE-2026-45757 PUBLISHED

Rocket.Chat: users.deactivateIdle` deactivates accounts without revoking existing login tokens

Assigner: GitHub_M
Reserved: 13.05.2026 Published: 24.06.2026 Updated: 25.06.2026

Rocket.Chat is an open-source, secure, fully customizable communications platform. 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.
