- CVE-2026-5060, 29 Jul 2026
- The MasterStudy LMS WordPress Plugin - for Online Courses and Education plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.14. This is due to the `stm_lms_delete_cover()` function lacking ownership validation on the `file_id` parameter before passing it to `wp_delete_attachment()`. This makes it possible for authenticated attackers, with Instructor-level access and above, to delete arbitrary attachments belonging to any user by enumerating sequential attachment IDs. CVE record
- CVE-2026-4817, 17 Apr 2026
- The MasterStudy LMS WordPress Plugin for Online Courses and Education plugin for WordPress is vulnerable to Time-based Blind SQL Injection via the 'order' and 'orderby' parameters in the /lms/stm-lms/order/items REST API endpoint in versions up to and including 3.7.25. This is due to insufficient input sanitization combined with a design flaw in the custom Query builder class that allows unquoted SQL injection in ORDER BY clauses. When the Query builder detects parentheses in the sort_by parameter, it treats the value as a SQL function and directly concatenates it into the ORDER BY clause without any quoting. While esc_sql() is applied to escape quotes and backslashes, this cannot prevent ORDER BY injection when the values themselves are not wrapped in quotes in the resulting SQL statement. This makes it possible for authenticated attackers, with subscriber-level access and above, to append arbitrary SQL queries via the ORDER BY clause to extract sensitive information from the database including user credentials, session tokens, and other confidential data through time-based blind SQL injection techniques. CVE record
- CVE-2026-0559, 14 Feb 2026
- The MasterStudy LMS WordPress Plugin - for Online Courses and Education plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'stm_lms_courses_grid_display' shortcode in all versions up to, and including, 3.7.11 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2025-13766, 6 Jan 2026
- The MasterStudy LMS WordPress Plugin - for Online Courses and Education plugin for WordPress is vulnerable to unauthorized modification and deletion of data due to a missing capability checks on multiple REST API endpoints in all versions up to, and including, 3.7.6.

- CVE-2024-3942, 2 May 2024
- The MasterStudy LMS WordPress Plugin - for Online Courses and Education plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to a missing capability check on several functions in versions up to, and including, 3.3.8. This makes it possible for authenticated attackers, with subscriber level permissions and above, to read and modify content such as course questions, post titles, and taxonomies. CVE record
- CVE-2024-3136, 9 Apr 2024
- The MasterStudy LMS plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.3.3 via the 'template' parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. CVE record
- CVE-2024-1904, 9 Apr 2024
- The MasterStudy LMS plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the search_posts function in all versions up to, and including, 3.2.13. This makes it possible for authenticated attackers, with subscriber-level access and above, to expose draft post titles and excerpts. CVE record
- CVE-2024-2409, 29 Mar 2024
- The MasterStudy LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.3.1. This is due to insufficient validation checks within the _register_user() function called by the 'wp_ajax_nopriv_stm_lms_register' AJAX action. This makes it possible for unauthenticated attackers to register a user with administrator-level privileges when MasterStudy LMS Pro is installed and the LMS Forms Editor add-on is enabled. CVE record
- CVE-2024-2411, 29 Mar 2024
- The MasterStudy LMS plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.3.0 via the 'modal' parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. CVE record
- CVE-2024-2106, 13 Mar 2024
- The MasterStudy LMS WordPress Plugin - for Online Courses and Education plugin for WordPress is vulnerable to Information Exposure in versions up to, and including, 3.2.10. This can allow unauthenticated attackers to extract sensitive data including all registered user's username and email addresses which can be used to help perform future attacks. CVE record
- CVE-2024-1512, 17 Feb 2024
- The MasterStudy LMS WordPress Plugin - for Online Courses and Education plugin for WordPress is vulnerable to union based SQL Injection via the 'user' parameter of the /lms/stm-lms/order/items REST route in all versions up to, and including, 3.2.5 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. CVE record
