Summary
Details

A shell injection flaw was found in pglogical in versions before 2.3.4 and before 3.6.26. An attacker with CREATEDB privileges on a PostgreSQL server can craft a database name that allows execution of shell commands as the postgresql user when calling pglogical.create_subscription().
