Parameter Value
CVSS 9.1 (CRITICAL)
Type CWE-1393 (Use of Default Password), CWE-1188, CWE-1327
Vendor PostgreSQL
Public PoC No

Deployment of the VPS.org one-click Supabase template deploys a PostgreSQL instance that is published on all interfaces (0.0.0.0:5432) with a default database password set to "postgres". Because Docker installs its own iptables rules, this exposure bypasses a standard host UFW configuration.
