Description

Vexa is an open-source, self-hostable meeting bot API and meeting transcription API. Prior to 0.10.0-260419-1910, the Vexa webhook feature allows authenticated users to configure an arbitrary URL that receives HTTP POST requests when meetings complete. The application performs no validation on the webhook URL, enabling Server-Side Request Forgery (SSRF).
