Description OSIDB Bzimport 2026-11-12 14:34:38 UTC 
Missing authorization in PostgreSQL DROP OWNED allows a role to remove itself from restrictive row level security policies, thereby reading or modifying rows that the policy was intended to deny, via queries after the DROP OWNED.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
