PostgreSQL Anonymizer vulnerability

What happened

PostgreSQL Anonymizer contains a SQL injection vulnerability in two import functions. A user can create a malicious JSON document containing specially crafted object names. If a superuser subsequently calls anon.import_database_rules() or anon.import_roles_rules(), the malicious code is executed with superuser privileges. The issue is fixed in PostgreSQL Anonymizer 3.1.4 and later
