Summary

In PostgreSQL, incorrect ownership assignment in the 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.

Risk Assessment

The risk is unauthorized modification or deletion of statistics objects by the table owner, which could lead to data integrity issues or incorrect query optimizer behavior.

Recommendation

It is recommended to upgrade PostgreSQL to version 18.5, 17.11, 16.15, 15.19, or 14.24 (or later) depending on the major version in use.
