Dialogflow agent developers with Webhook editor permission are able to configure Webhooks using Dialogflow service agent access token authentication.
This allows the attacker to escalate their privileges from agent-level to project-level, granting them unauthorized access to manage resources in services associated with the project, leading to unexpected costs and resource depletion for the producer project.
A fix was applied on the server side to protect from this vulnerability in February 2025. No customer action is required.
