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.

CVE-2020-25694 [HIGH] PostgreSQL vulnerabilities
Title: PostgreSQL vulnerabilities
Summary: Several security issues were fixed in PostgreSQL.
Peter Eisentraut discovered that PostgreSQL incorrectly handled connection
security settings. Client applications could possibly be connecting with
certain security parameters dropped, contrary to expectations.
(CVE-2020-25694)
Etienne Stalmans discovered that PostgreSQL incorrectly handled the
security restricted operation sandbox. An authenticated remote attacker
could possibly use this issue to execute arbitrary SQL functions as a
superuser. (CVE-2020-25695)
Nick Cleaton discovered that PostgreSQL incorrectly handled the \gset
meta-command. A remote attacker with a compromised server could possibly
use this issue to execute arbitrary code. (CVE-2020-25696)
