CVE-2026-45631
CWE-798Published: May 29, 2026· Updated: Jun 1, 2026
Official 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.
Risk Analysis
Dokploy, a Platform as a Service (PaaS), in versions from 0.27.0 to before 0.29.3, contains a critical hardcoded secret vulnerability. An unauthenticated attacker can exploit a fallback secret to forge email verification JWTs, gain administrative access, and execute commands on the host via the built-in SSH terminal. The CVSS score of 10.0 indicates the highest possible severity, allowing complete unauthenticated remote compromise.
No public exploit is currently known. This vulnerability is remotely exploitable (AV:N) without any authentication (PR:N) and has low attack complexity.
Immediately upgrade Dokploy to version 0.29.3 or later to eliminate the hardcoded secret. Ensure all secrets are properly managed and not hardcoded in application logic.
Technical Analysis
CVE-2026-45631 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
