CVE-2026-72919: CWE-862: Missing Authorization in RocketChat Rocket.Chat
Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to 7.10.14, 8.0.8, 8.1.7, 8.2.7, 8.3.7, 8.4.5, 8.5.2, and 8.6.1, the channels.convertToTeam REST endpoint allows an authenticated registered user with the create-team permission to convert an unrelated public channel by supplying channelName instead of channelId because the edit-room permission is checked only for channelId. This issue is fixed in versions 7.10.14, 8.0.8, 8.1.7, 8.2.7, 8.3.7, 8.4.5, 8.5.2, and 8.6.1.

Technical Summary
Rocket.Chat versions prior to 7.10.14, 8.0.8, 8.1.7, 8.2.7, 8.3.7, 8.4.5, 8.5.2, and 8.6.1 contain a missing authorization vulnerability (CWE-862) in the channels.convertToTeam REST endpoint. An authenticated user with create-team permission can convert an unrelated public channel by supplying channelName instead of channelId because the permission check for edit-room is only enforced on channelId. This allows unauthorized modification of channels. The vulnerability is resolved in the listed fixed versions.
Potential Impact
The vulnerability allows an authenticated user with create-team permission to convert public channels they should not have permission to modify, potentially leading to unauthorized changes in channel structure or membership. There is no direct confidentiality or availability impact reported. The CVSS score is 4.3 (medium severity), indicating limited impact primarily on integrity.
Mitigation Recommendations
A fix is available in Rocket.Chat versions 7.10.14, 8.0.8, 8.1.7, 8.2.7, 8.3.7, 8.4.5, 8.5.2, and 8.6.1. Users should upgrade to one of these versions or later to remediate this vulnerability. No other mitigation guidance is provided or necessary as the issue is resolved by the official patches.
