Description
CVE-2026-116311 is a vulnerability in PostgreSQL where missing authorization in the DROP OWNED command allows a role to remove itself from restrictive row level security policies. This enables the role to read or modify rows that the policy was intended to deny after executing DROP OWNED. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
