Title
Dockhand < 1.0.40 Unauthenticated Webhook Trigger via Git Webhook Endpoints
Summary
Dockhand before 1.0.40 contains an authentication bypass vulnerability in its git webhook endpoints that allows unauthenticated remote attackers to trigger arbitrary stack redeployments by exploiting a null webhook secret guard condition. Attackers can enumerate sequential stack IDs and send unsigned webhook requests to force git clone and docker compose operations, enabling denial of service or, when combined with write access to the tracked git branch, container escape and full host compromise via attacker-controlled docker-compose.yml with privileged bind mounts.
