Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Tutor LMS Pro plugin for WordPress is vulnerable to unauthorized access of data, modification of data, loss of data due to a missing capability check on the 'get_calendar_materials' function. The plugin is also vulnerable to SQL Injection via the ‘year’ parameter of that function due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Tutor LMS Pro WordPress plugin has a missing capability check on the 'get_calendar_materials' function, allowing any authenticated user with subscriber-level permissions to access this function. Additionally, the 'year' parameter in this function is vulnerable to SQL injection due to insufficient input sanitization and lack of prepared SQL statements, enabling attackers to inject and execute arbitrary SQL queries.

MitigationUpdate to a patched version of Tutor LMS Pro that adds proper capability checks and uses prepared statements for the SQL query in the 'year' parameter.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Tutor LMS plugin installation and version
    Check the installed version of the Tutor LMS plugin in WordPress via plugin admin page, wp-content/plugins/tutor folder, or by querying the wp_options table for 'tutor_version' option
    Affected if The installed version is any version below 2.7.1 (e.g., 2.7.0, 2.6.x, etc.)
  2. Confirm WordPress user roles exist
    Review WordPress user roles via Users admin panel or query wp_users and wp_usermeta tables to check for users with subscriber, contributor, author, editor, or administrator roles
    Affected if Any user account exists with subscriber-level permissions or higher (subscriber, contributor, author, editor, administrator)
  3. Check if Tutor LMS Pro add-on is active
    Check if the Pro version is installed by looking for the tutor-pro folder in wp-content/plugins/ or checking for pro-specific options in wp_options table
    Affected if Tutor LMS Pro is installed and active, regardless of version (the vulnerability exists in Pro versions before 2.7.1)
  4. Inspect AJAX endpoint accessibility
    Test access to the get_calendar_materials AJAX action (typically /wp-admin/admin-ajax.php?action=get_calendar_materials) using a low-privilege authenticated user session
    Affected if The AJAX endpoint responds without returning a capability error (401/403) when accessed by a subscriber-level user, indicating the missing authorization check is present

A user is affected if they have Tutor LMS Pro installed with a version below 2.7.1 AND have any authenticated user accounts on their WordPress site, because the combination enables unauthenticated/weak-authorization SQL injection exploitation.
