Description Srikanth Balasubramanian 2026-09-02 07:29:34 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.

Incorrect ownership assignment in PostgreSQL ALTER TABLE ALTER TYPE command reassigns ownership of dependent statistics objects to the current user.  This wrongly allows the table owner to run DROP STATISTICS and ALTER STATISTICS via this improper ownership.  It wrongly denies those commands to the prior statistics object owner.  DROP TABLE remains able to remove statistics objects, so this exploit achieves nothing in many ownership arrangements.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
