Description
This security bulletin contains information about 1 vulnerability.
1) Untrusted search path (CVE-ID: CVE-2020-14349)
CWE-ID: CWE-426 - Untrusted Search Path

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.
