Description

The vulnerability allows a remote user to escalate privileges within the database.

The vulnerability exists due to the way PostgreSQL handles search_path during replications. Users of a replication publisher or subscriber database can create objects in the public schema and harness them to execute arbitrary SQL functions under the identity running replication, often a superuser.


Remediation

Install updates from vendor's website.
