Technical Description
pgx is a PostgreSQL driver and toolkit for Go. SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control. The problem is resolved in v4.18.2 and v5.5.4. As a workaround, reject user input large enough to cause a single query or bind message to exceed 4 GB in size.
Remediation
Check the references section for vendor advisories and patches from jackc. Update pgproto3 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
