What it is stated by the CNA
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.

How to check this
Every value above is held with two dates: when it was true upstream (as_of) and when we recorded it (tx_from). Re-derive the exploit probability as it stood on any date:
SELECT value, source, source_version, as_of, tx_from
FROM volatile_valid_as_of('CVE-2025-22248', '2026-10-30T23:59:59.999999Z', now());
