Until an official patch is available, restrict access to the vulnerable endpoint and monitor for suspicious cancellation requests if possible.
Description
WWBN AVideo versions up to and including 29.0 contain an authorization bypass vulnerability in the PayPal billing agreement cancellation endpoint. A low-privilege authenticated user can supply another user's PayPal billing agreement ID to cancel that user's recurring subscription without ownership verification. This can lead to revenue loss for the platform and loss of paid service for the victim. A fix has been committed but no official patch or vendor advisory is currently confirmed.
