Summary
The HEL Online Classroom: AI-powered Online Classrooms WordPress plugin through 1.0.3 does not perform any authorisation check on one of its REST API routes. This allows unauthenticated users to retrieve its stored settings, including the shared secret used to sign API requests to the connected BigBlueButton server.
Risk Assessment
Exposure of the shared secret may allow an attacker to impersonate the server and manipulate BigBlueButton sessions, potentially leading to unauthorized access to meetings.
Recommendation
Update the plugin to the latest version if available, or temporarily disable the REST API route that exposes settings. Additionally, change the shared secret and monitor logs for unauthorized requests.
