The WP Hotel Booking WordPress plugin before 2.0.8 does not have authorisation and CSRF checks, as well as does not ensure that the package to be deleted is a package, allowing any authenticated users, such as subscriber to delete arbitrary posts
The WP Hotel Booking plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.10.1. This is due to missing or incorrect nonce validation on the admin_add_order_item() function. This makes it possible for unauthenticated attackers to add an order item via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
The LearnPress WordPress plugin before 4.1.7.2 unserialises user input in a REST API endpoint available to unauthenticated users, which could lead to PHP Object Injection when a suitable gadget is present, leadint to remote code execution (RCE). To successfully exploit this vulnerability attackers must have knowledge of the site secrets, allowing them to generate a valid hash via the wp_hash() function.
