What is CVE-2025-22248?
CVE-2025-22248 is a critical authentication bypass vulnerability in VMware Bitnami, published on 13 May 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The bitnami/pgpool Docker image, and the bitnami/postgres-ha k8s chart, under default configurations, comes with an 'repmgr' user that allows unauthenticated access to the database inside the cluster. The PGPOOL_SR_CHECK_USER is the user that Pgpool itself uses to perform streaming replication checks against nodes, and should not be at trust level. This allows to log into a PostgreSQL database using the repgmr user without authentication. If Pgpool is exposed externally, a potential attacker could use this user to get access to the service. This is also present within the bitnami/postgres-ha Kubernetes Helm chart.
Weakness: CWE-1188
