NVD description
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.

CVE-2026-53988 is a maximum severity flaw in Finsys's Dockhand, CVSS 10.0. A null webhook secret lets unauthenticated attackers force git clone and docker builds, and with write access to the tracked branch it escalates to container escape and full host takeover. VulnTracker recommends upgrading to Dockhand 1.0.40 immediately, this one needs no login at all. Details: http://vulntracker.io/cves/CVE-2026-53988 #Dockhand #CVE #InfoSec #DevOps
