Mitigation checklist
- To mitigate this issue, restrict network access to the PgBouncer service to only trusted clients or the local host. This can be achieved by configuring firewall rules to limit incoming connections to the PgBouncer port. Ensure that any changes to network configurations are applied and services are reloaded or restarted as necessary, which may temporarily disrupt existing connections.
