Chat Privacy Bypass in BigBlueButton Web Conferencing Software

CVE-2020-27601

What is CVE-2020-27601?

In BigBlueButton versions prior to 2.2.7, a vulnerability exists where the 'lockSettingsProps.disablePrivateChat' setting fails to restrict access to already opened private chat rooms. This means that even with the setting enabled to disable private chats, users can still access those that are already active, undermining intended privacy measures. This flaw can potentially expose private conversation content to unauthorized participants, creating a risk for sensitive information leakage. Users are advised to update to version 2.2.7 or later to mitigate this issue.
