Doc Text:
A flaw was found in PostgreSQL, where it did not properly sanitize the search_path during logical replication. This flaw allows an authenticated attacker to use this flaw in an attack similar to CVE-2018-1058 to execute an arbitrary SQL command in the user's context for replication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Description Dhananjay Arunesh 2020-08-04 03:48:13 UTC 
The PostgreSQL search_path setting determines schemas searched for tables, functions, operators, etc.  The CVE-2018-1058 fix caused most PostgreSQL-provided client applications to sanitize search_path, but logical replication continued to leave search_path unchanged.  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.  Installations having adopted a documented "secure schema usage pattern" are not vulnerable.

Comment 10 Hardik Vyas 2020-09-08 08:07:43 UTC 
Statement:

In Red Hat Gluster Storage 3, PostgreSQL was shipped as a part of Red Hat Gluster Storage Console that is no longer supported for use with Red Hat Gluster Storage 3.5. Red Hat Gluster Storage Web Administration is now the recommended monitoring tool for Red Hat Storage Gluster clusters.
