Description Srikanth Balasubramanian 2026-08-27 10:18:15 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.

Missing authorization in PostgreSQL logical decoding allows a non-superuser holding REPLICATION privilege to dlopen any file visible to the operating system account running the server, via the choice of logical decoding plugin.  This in turn runs arbitrary code as that account.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
