CVE-2026-45757

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

Published Jun 24, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed

Description

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.
