    "summary": "PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a JSON document and placing malicious code inside a particular key-value pair. If a superuser calls the import_database_rules() or import_roles_rules() functions, the malicious code is executed with superuser privileges. The problem is resolved in PostgreSQL Anonymizer 3.1.1 and further versions",
