First published: Fri Nov 12 2021(Updated: )
PostgreSQL is vulnerable to a man-in-the-middle attack, caused by improper validation of user-supplied input by libpq. A remote attacker could exploit this vulnerability to launch a man-in-the-middle attack to inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption.
