Information disclosure vulnerability exists in pg_ivm versions prior to 1.5.1. An Incrementally Maintainable Materialized View (IMMV) created by pg_ivm 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.

pg_ivm provided by IVM Development Group is a PostgreSQL extension module that provides incremental view maintenance functionality of materialized views. pg_ivm contains multiple vulnerabilities listed below. <ul><li>Exposure of sensitive information to an unauthorized actor (CWE-200) - CVE-2023-22847 An Incrementally Maintainable Materialized View (IMMV) created by pg_ivm may reflect rows with Row-Level Security that the owner of the IMMV should not have access to.</ul> <ul><li>Uncontrolled search path element (CWE-427) - CVE-2023-23554 When refreshing an IMMV, pg_ivm executes functions without specifying schema names. Under certain conditions, pg_ivm may be tricked to execute unexpected functions from other schemas with the IMMV owner's privilege.</ul> IVM Development Group reported these vulnerabilities to IPA to notify users of its solution through JVN. JPCERT/CC and IVM Development Group coordinated under the Information Security Early Warning Partnership.
