A vulnerability was detected in rowboatlabs rowboat up to 0.9.1. The impacted element is the function request.text/req.json of the file apps/rowboat/app/api/composio/webhook/route.ts of the component Composio Webhook Endpoint. The manipulation results in denial of service. It is possible to launch the attack remotely. The exploit is now public and may be used. Upgrading to version 0.9.2 is sufficient to resolve this issue.
