Detailsinfo

A vulnerability classified as problematic has been found in CloudNative-PG CloudNativePG up to 1.28.3/1.29.1. Affected is the function SetUserPassword of the file pkg/management/postgres/utils/roles.go of the component Roles. The manipulation with an unknown input leads to a missing encryption vulnerability. CWE is classifying the issue as CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-55765 since 06/17/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely.
