The Motors WordPress plugin before 1.4.124 does not properly verify that a user is authorised to modify a listing before processing one of its listing management actions, allowing authenticated attackers with subscriber-level access and above to set metadata on posts they do not own, including overwriting product prices. Exploitation is possible only when WooCommerce is active and the Motors WordPress plugin before 1.4.124's paid featured-listing option is enabled, neither of which is a default configuration.
