How to fix?

Upgrade org.postgresql:postgresql to version 42.7.6 or higher.

Overview

org.postgresql:postgresql is a Java JDBC 4.2 (JRE 8+) driver for PostgreSQL database.

Affected versions of this package are vulnerable to Insertion of Sensitive Information Into Sent Data in the process of handling GSS-encrypted connections when writing large values from a byte array. An attacker can cause unintended data to be stored on the server by sending crafted input that triggers the reuse of previous message bytes instead of the intended value. This is only exploitable if GSS encryption is enabled (gssEncMode set to prefer or require) and large values are written using affected methods.
