{"cve":"CVE-2026-55765","nvd":{"published":"2026-08-20T22:17:22.487","modified":"2026-10-26T10:10:00.140","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.5},"cwes":["CWE-256","CWE-522"],"references":["https://github.com/cloudnative-pg/cloudnative-pg/commit/2f0342747e1f160425b9d51753c0069b0d6117d5","https://github.com/cloudnative-pg/cloudnative-pg/commit/3cd5af5d388c26758acf13c19ea806b4bcebb3fe","https://github.com/cloudnative-pg/cloudnative-pg/commit/9a13573dbe3d78721b7ea92141e6d2324a2c0ef0","https://github.com/cloudnative-pg/cloudnative-pg/pull/10724","https://github.com/cloudnative-pg/cloudnative-pg/releases/tag/v1.28.4"],"products":[],"source":"nvd","synced_at":"2026-10-26T10:28:23.151169805+00:00"},"epss":{"cve":"CVE-2026-55765","score":0.005,"percentile":0.42549,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
