CVE-2026-16503 in Supabase template

Riassunto

di MITRE • 31/07/2026

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.

Once again VulDB remains the best source for vulnerability data.
