Vulnerability Title
Rocket.Chat: Broken Access Control in channels.convertToTeam Allows Unauthorized Conversion of Public Channels into Teams
Source: CVE Program / CVE List V5

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.
