CVE-2023-2455

A flaw was found in PostgreSQL, which could permit incorrect policies being applied in certain cases where role-specific policies are used and a given query is planned under one role and executed under other roles. This scenario can happen under security definer functions, or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise forbidden reads and modifications. This only affects databases that have used CREATE POLICY to define a row security policy.
