The LearnPress plugin for WordPress is vulnerable to time-based SQL Injection via the ‘order_by’ parameter in all versions up to, and including, 4.2.5.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The LearnPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.2.5.7 via the /wp-json/lp/v1/profile/course-tab REST API due to missing validation on the 'userID' user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve the details of another user's course progress.

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.

The LearnPress WordPress plugin before 4.1.6 does not sanitise and escape the lp-dismiss-notice before outputting it back via the lp_background_single_email AJAX action, leading to a Reflected Cross-Site Scripting

Users of the LearnPress WordPress plugin before 4.1.5 can upload an image as a profile avatar after the registration. After this process the user crops and saves the image. Then a "POST" request that contains user supplied name of the image is sent to the server for renaming and cropping of the image. As a result of this request, the name of the user-supplied image is changed with a MD5 value. This process can be conducted only when type of the image is JPG or PNG. An attacker can use this vulnerability in order to rename an arbitrary image file. By doing this, they could destroy the design of the web site.

The LearnPress WordPress plugin before 4.1.4 does not sanitise, validate and escape the id parameter before using it in SQL statements when duplicating course/lesson/quiz/question, leading to SQL Injections issues
