Analysis

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. CVSS Score: 10. Published: 2026-09-29T20:17:20.403.

The EU is recommending import controls to combat unregulated squid fishing in the Southwest Atlantic. I’m not optimistic. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Blog moderation policy.
