Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

Uncontrolled search path element in PostgreSQL CREATE EXTENSION allows an attacker with database-level CREATE privilege to execute arbitrary code as the bootstrap superuser, via ALTER SCHEMA ... RENAME or CREATE EXTENSION ... SCHEMA "$user". ALTER EXTENSION was also affected. A trusted-extension script located the wrong object and executed arbitrary SQL of the attacker's choice. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
