Vulnerability

A vulnerability has been identified in Rasa Pro where voice connectors in Rasa Pro do not properly implement authentication even when a token is configured in the credentials.yml file. This could allow an attacker to submit voice data to the Rasa Pro assistant from an unauthenticated source.

This impacts the following connectors:

• audiocodes_stream
• genesys
• jambonz

As part of our investigation to resolve this issue, we have also performed a security review of our other voice channel connectors:

• browser_audio: Does not support authentication. This is a development channel not intended for production use.
• twilio_media_streams, twilio_voice and jambonz: Authentication is currently not supported by these channels, but our investigation has found a way for us to enable it for these voice channel connectors in a future Rasa Pro release.

Fix

The issue has been resolved for audiocodes, audiocodes_stream, and genesys connectors. Fixed versions of Rasa Pro have been released for 3.9.20, 3.10.19, 3.11.7 and 3.12.6. Please update to a fixed release.

If you are using one of the affected connectors, we strongly recommend upgrading to a fixed version. For connectors where authentication is not supported (e.g., Twilio), we suggest taking extra caution and considering other compensating controls if applicable.
