Security readout for executives and security teams
This is a PostgreSQL privilege-escalation issue. A user who can create databases or roles may be able to become a database superuser by using specially crafted database or role names. The main business risk is unauthorized control of older PostgreSQL databases where these elevated creation privileges were granted too broadly. Exposure is limited to affected PostgreSQL versions and authenticated accounts holding CREATEDB or CREATEROLE. Internet exposure alone is not sufficient without valid credentials and those privileges. Prioritize remediation for production PostgreSQL systems that are old and have non-administrative users with database or role creation rights. This is less urgent where creation privileges are tightly restricted, but the impact can be severe. Mitigation focus: Upgrade PostgreSQL to 9.1.23, 9.2.18, 9.3.14, 9.4.9, 9.5.4, or later.; Apply distribution vendor security updates from Red Hat, Debian, Gentoo, or your PostgreSQL package source.; Remove CREATEDB and CREATEROLE from accounts that do not strictly need them..
