NVD Description

Note: Versions mentioned in the description apply only to the upstream cloudnative-pg-plugin-barman-cloud-fips-0.11 package and not the cloudnative-pg-plugin-barman-cloud-fips-0.11 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

CloudNativePG is a platform designed to manage PostgreSQL databases within Kubernetes environments. Prior to 1.29.1 and 1.28.3, 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 pg_monitor. SET ROLE changes only current_user; session_user remains postgres. Any SQL expression evaluated inside the scrape session can invoke RESET ROLE to recover real superuser privileges, then use COPY ... TO PROGRAM to spawn an OS-level subprocess as the postgres user inside the primary pod. The READ ONLY transaction flag does not block this; it gates writes to database state, not external processes. This vulnerability is fixed in 1.29.1 and 1.28.3.
