Overview

Affected versions of this package are vulnerable to Improper Preservation of Consistency Between Independent Representations of Shared State due to incomplete tracking of changes in role membership, role attributes, and database ownership in the plan reuse process. An attacker can access or modify data that should no longer be permitted by leveraging cached row-level security policies after privilege changes, until the cache is invalidated or the session ends. This is only exploitable if an application removes privileges or changes row security policies during an active session.
