CVE-2026-116817: OpenPanel missing authentication in Bull Board

CVE-2026-116817 · Severity: medium · CVSS 6.5 · Published 2026-10-27

OpenPanel is a control panel for managing server infrastructure and applications. Versions before 3.0.0 fail to require authentication for the Bull Board job queue dashboard, allowing unauthenticated attackers to view queue data and manipulate jobs (add, retry, or delete them). An attacker can exploit this to disrupt application services or extract sensitive information stored in job queues.

How to fix

  • Fixed in: 3.0.0

Set ADMIN_USERNAME and ADMIN_PASSWORD environment variables to enable authentication for Bull Board, or set DISABLE_BULLBOARD=true to disable the queue UI entirely until credentials are configured.

Technical details

OpenPanel serves a Bull Board dashboard on its worker HTTP port without enforcing authentication when operator credentials (ADMIN_USERNAME and ADMIN_PASSWORD) are not configured. The vulnerability allows unauthenticated access to `/api/queues` and mutating Bull Board APIs. An attacker with network access can read queue metrics, datastore health, and job data, or modify job states. The fix in 3.0.0 requires operator credentials to mount the Bull Board dashboard at all.
