Dokploy: Pre-Auth Admin Takeover via Hardcoded Authentication Secret

Published May 29, 2026 · Updated Jun 1, 2026 · Assigned by GitHub_M

Description

Dokploy is a free, self-hostable Platform as a Service (PaaS). From 0.27.0 to before 0.29.3, a hardcoded BETTER_AUTH_SECRET fallback ("better-auth-secret-123456789") lets an unauthenticated attacker forge email verification JWTs, trigger auto-sign-in as admin, and execute commands on the host via the built-in SSH terminal. This vulnerability is fixed in 0.29.3.
