Answer in brief
CVE-2026-55765 records a Unknown severity vulnerability in CloudNativePG: Cleartext role passwords recorded in pg_stat_statements allow privileged tenant roles to recover the PostgreSQL superuser credential and achieve RCE in the database pod. The current sources do not mark it as known exploited. The current feed maps cloudnative-pg/cloudnative-pg (generic). Check affected ranges and fixed versions before updating.

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.
