Description Jon Weiser 2026-07-13 17:00:00 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

SQL injection in PostgreSQL pg_createsubscriber allows an attacker with pg_create_subscription rights to execute arbitrary SQL as a superuser.  The attack takes effect when pg_createsubscriber next runs.  Within major versions 17 and 18, minor versions before PostgreSQL 18.4 and 17.10 are affected.  Versions before PostgreSQL 17 are unaffected.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
