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.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
