CVE-2020-4230
IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.1 and 11.5 is vulnerable to an escalation of privilege when an authenticated local attacker with special permissions executes specially crafted Db2 commands.
Does this matter?
Lower severity and a low EPSS score (0.38%). Track it; it rarely justifies an emergency change on its own.
