Listar – Directory Listing & Classifieds WordPress Plugin <= 3.0.0 - Missing Authorization to Authenticated (Subscriber+) Listing Update

The Listar – Directory Listing & Classifieds WordPress Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the '/wp-json/listar/v1/place/save' REST API endpoint in all versions up to, and including, 3.0.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update listing details.
