Uncontrolled search path element vulnerability exists in pgivm versions prior to 1.5.1. When refreshing an IMMV, pgivm executes functions without specifying schema names. Under certain conditions, pgivm may be tricked to execute unexpected functions from other schemas with the IMMV owner's privilege. If this vulnerability is exploited, an unexpected function provided by an attacker may be executed with the privilege of the materialized view owner.

Information disclosure vulnerability exists in pgivm versions prior to 1.5.1. An Incrementally Maintainable Materialized View (IMMV) created by pgivm may reflect rows with Row-Level Security that the owner of the IMMV should not have access to. As a result, information in tables protected by Row-Level Security may be retrieved by a user who is not authorized to access it.
