CVE-2022-1552 Information

Description

A flaw was found in PostgreSQL. There is an issue with incomplete efforts to operate safely when a privileged user is maintaining another user’s objects. The Autovacuum REINDEX CREATE INDEX REFRESH MATERIALIZED VIEW CLUSTER and pg_amcheck commands activated relevant protections too late or not at all during the process. This flaw allows an attacker with permission to create non-temporary objects in at least one schema to execute arbitrary SQL functions under a superuser identity.
