CVE-2026-6469
Last modified
CVE-2026-6469 is a low-severity vulnerability rated 3.8/10 on the CVSS scale. 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. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
Description
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 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
