CVE-2026-55762: CWE-862: Missing Authorization in RocketChat Rocket.Chat
A missing authorization vulnerability exists in Rocket.Chat versions prior to 7.10.13, 8.0.7, 8.1.6, 8.2.6, 8.3.6, 8.4.4, and 8.5.1 in the POST /api/v1/fingerprint REST endpoint. Although authentication is required, the endpoint does not verify user authorization, allowing any authenticated user, including those with standard user roles, to deregister the workspace from Rocket.Chat Cloud. This action removes cloud credentials, the workspace license, and disables push notifications, requiring manual re-registration to restore functionality. The vulnerability has a high severity with a CVSS score of 8.1. Fixed versions addressing this issue are 7.10.13, 8.0.7, 8.1.6, 8.2.6, 8.3.6, 8.4.4, and 8.5.1.
AI Analysis
Technical Summary
Rocket.Chat contains a missing authorization vulnerability (CWE-862) in the POST /api/v1/fingerprint REST endpoint. While the endpoint enforces authentication, it does not perform authorization checks, allowing any authenticated user to invoke the endpoint with the payload {"setDeploymentAs": "new-workspace"}. This causes permanent deregistration of the workspace from Rocket.Chat Cloud, wiping cloud credentials, removing the workspace license, and breaking push notifications for all users. Recovery requires manual re-registration. The issue affects versions prior to 7.10.13, 8.0.7, 8.1.6, 8.2.6, 8.3.6, 8.4.4, and 8.5.1, where it has been fixed.
Potential Impact
Exploitation allows any authenticated user, including those with standard user roles, to deregister the workspace from Rocket.Chat Cloud. This results in loss of cloud credentials, removal of the workspace license, and disruption of push notifications for all users. The workspace must be manually re-registered to restore normal operation. There is no confidentiality impact, but integrity and availability are severely affected.
Mitigation Recommendations
Upgrade Rocket.Chat to version 7.10.13, 8.0.7, 8.1.6, 8.2.6, 8.3.6, 8.4.4, or 8.5.1 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor advisory.
