How to fix?

Upgrade org.postgresql:postgresql to version 42.3.3 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 Arbitrary Code Injection. DISPUTED

When an arbitrary filename is specified in the loggerFileName connection parameter jdbc:postgresql://localhost:5432/test?user=test&password=test&loggerLevel=DEBUG&loggerFile=./blah.jsp&<%Runtime.getRuntime().exec(request.getParameter("i"));%>, a valid JSP file is created and a Remote Code Execution could be performed.

Note: the vendor's position is that there is no pgjdbc vulnerability; instead, it is a vulnerability for any application to use the pgjdbc driver with untrusted connection properties.
