Summary
A missing authorization vulnerability was found in the Event-Driven Ansible (EDA) websocket API.

Any authenticated user can send a forged message with an arbitrary activation_id to receive plaintext credentials associated with that activation, including OAuth tokens, vault passwords, and SSH keys.
