A privilege escalation vulnerability exists in Google Cloud's Dialogflow CX.
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.
