Mitigation checklist
- To mitigate the risk associated with this flaw, restrict network access to the PostgreSQL server to only trusted hosts and networks. This reduces the attack surface and limits the ability of unauthorized users to establish connections that could bypass GSSAPI enforcement via direct TLS. *Warning:* Restricting network access may impact legitimate client connections if not configured carefully. Changes to firewall rules or network configurations may require a service reload or restart to take effect.
