CVE-2026-55765 PUBLISHED CVSS 8.5 HIGH

Reported by GitHub_M · Published August 20, 2026

CloudNativePG is a platform designed to manage PostgreSQL databases within Kubernetes environments. Prior to 1.28.4 and 1.29.2, CloudNativePG embedded cleartext role passwords in `ALTER ROLE` and `CREATE ROLE` statements generated by SetUserPassword in pkg/management/postgres/utils/roles.go and appendPasswordOption in internal/management/controller/roles/postgres.go. When pg_stat_statements was preloaded with track_utility enabled and an untrusted tenant held pg_monitor or pg_read_all_stats, the tenant could recover platform-managed superuser or application-owner passwords, reconnect through enabled superuser TCP access, and execute operating system commands in the database pod with `COPY ... FROM PROGRAM`. Clusters using SCRAM-SHA-256 verifiers in managed-role Secrets were not affected. This issue is fixed in versions 1.28.4, 1.29.2, and 1.30.0.
