Description Pedro Sampaio 2021-04-27 15:36:35 UTC
A flaw was found in pglogical 2.3.3 and earlier, 3.6.25 and earlier. A user having CREATEDB privilege on a PostgreSQL server can craft a database name that allows execution of shell commands as the postgresql user when calling pglogical.create_subscription().

Comment 1 Yadnyawalk Tale 2021-04-28 11:27:28 UTC
Red Hat CloudForms do not ship pglogical 5.11 onward, thus CFME is not affected to the flaw. The rubygem-pg-pglogical (https://github.com/ManageIQ/pg-pglogical) is different than rh-postgresql95-postgresql-pglogical (https://github.com/2ndQuadrant/pglogical) package.
