CVE-2026-16503

CriticalCVSS 9.1
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Low risk
0.14%

4th percentile - higher than 4% of all known CVEs

Summary

Deployment of the VPS.org one-click Supabase template runs a PostgreSQL instance listening 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.

Risk Assessment

An attacker from the external network can gain unauthorized access to the PostgreSQL database, potentially leading to data leakage, modification, or deletion.

Recommendation

Immediately change the default database password, configure PostgreSQL to listen only on localhost (127.0.0.1), and adjust Docker firewall rules.
