NVD Description

Note: Versions mentioned in the description apply only to the upstream libpq-devel package and not the libpq-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
