Statistics privilege changes via ownership reassignment
Published Aug 13, 2026 · Updated Aug 13, 2026
Incorrect ownership assignment in PostgreSQL before 18.6, 17.11, 16.15, 15.19, and 14.24 allows remote authenticated users to alter statistics. The ALTER TABLE ALTER TYPE path assigns each dependent extended-statistics object to the command's current user instead of preserving its owner. Exploitation requires a role that owns the table while another role owns dependent statistics; it enables unauthorized ALTER STATISTICS or DROP STATISTICS, although DROP TABLE already removes them in many ownership arrangements.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <14.24
- Affected versionversion=15 <15.19
- Affected versionversion=16 <16.15
- Affected versionversion=17 <17.11
