CVE-2026-45757 Details
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.
A session-revocation vulnerability exists in Rocket.Chat versions 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. The issue arises when users are deactivated for idleness through the 'users.deactivateIdle' function. In such cases, the deactivated users can still access authenticated REST endpoints using their previously issued login tokens. This occurs because the deactivation process does not revoke the login tokens, allowing continued API access until the tokens are manually removed.
Users can update to Rocket.Chat versions 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8, or 7.10.12 to address this vulnerability.
