Privilege Escalation

CloudNativePG is vulnerable to Privilege Escalation. The vulnerability is due to the metrics exporter establishing PostgreSQL sessions as the postgres superuser and relying on SET ROLE for privilege reduction, which allows an attacker to restore superuser privileges using RESET ROLE and execute...

GHSA-423P-G724-FR39 CloudNativePG's metrics exporter allows privilege escalation to PostgreSQL superuser and OS RCE

Impact The CloudNativePG metrics exporter opens its PostgreSQL connection as the postgres superuser via the pod-local Unix socket, then demotes the session with SET ROLE pgmonitor. SET ROLE changes only currentuser; sessionuser remains postgres. That residual superuser identity is the foothold fo...
