Vulnerability A vulnerability has been identified in Rasa Pro and Rasa Open Source that enables an attacker who has the ability to load a maliciously crafted model remotely into a Rasa instance to achieve Remote Code Execution. The prerequisites for this are: – The HTTP API must be enabled on the Rasa instance eg with –enable-api. This is not the default configuration. – For unauthenticated RCE to be exploitable, the user must not have configured any authentication or other security controls recommended in our documentation. – For authenticated RCE, the attacker must posses a valid authentication token or JWT to interact with the Rasa API. Fix We encourage you to upgrade to a version of Rasa that includes a fix. These are: Rasa Pro 3.8.18, 3.9.16, 3.10.12 Rasa Open Source 3.6.21 Once you have upgraded your Rasa Pro or Open Source installation, you will need to retrain your model using the fixed version of Rasa Pro or Open Source. If you have a custom component that inherits from one of the components listed below and modified the persist or load method, make sure to update your code.
