Summary

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. The overall impact is limited, as standard DROP TABLE operations still correctly remove the affected objects.

Mitigation checklist

Recommended fix / mitigation

To mitigate this, limit the ALTER TABLE ALTER TYPE command to trusted database users. If the command must be used, manually review and restore the correct ownership of any affected extended statistics objects. Additionally, relying on standard DROP TABLE commands for routine object removal safely avoids the primary impacts of this flaw.
