CVE-2021-4388

Date: July 1, 2023

The Opal Estate plugin for WordPress is vulnerable to featured property modifications in versions up to, and including, 1.6.11. This is due to missing capability checks on the opalestate_set_feature_property() and opalestate_remove_feature_property() functions. This makes it possible for unauthenticated attackers to set and remove featured properties.
