CVE-2026-45631 Details
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.
A vulnerability in Dokploy versions 0.27.0 through 0.28.8 allows unauthenticated attackers to exploit a hardcoded fallback for the BETTER_AUTH_SECRET. This secret enables the forging of email verification JSON Web Tokens (JWTs), which can be used to trigger automatic sign-ins as an admin. Once signed in, the attacker can execute commands on the host through the built-in SSH terminal. The vulnerability arises because the hardcoded secret is shared across all default self-hosted instances, and the email verification process does not require a database lookup, allowing for unauthorized admin access.
Users can upgrade to Dokploy version 0.29.3 or later, where this vulnerability has been fixed.
