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
Authorization Bypass Through User-Controlled Key vulnerability in Themeum Tutor LMS tutor allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Tutor LMS: from n/a through <= 3.9.13.

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 · moderate confidence

Authorization bypass vulnerability in Themeum Tutor LMS where user-controlled input in access control checks allows attackers to circumvent security levels and gain unauthorized access to protected functionality. The flaw stems from incorrectly configured access control logic that relies on user-manipulatable parameters.

MitigationUpdate Tutor LMS to version 3.9.14 or later which contains the security patch. Additionally, review and harden access control implementations to ensure all authorization decisions are based on server-side validation of authenticated sessions rather than user-controllable parameters.

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. Identify installed Tutor LMS version
    Locate the main plugin file (tutor.php) in wp-content/plugins/tutor and open it to read the version header comment, or query the WordPress database: SELECT option_value FROM wp_options WHERE option_name = 'tutor_version'
    Affected if version is present and is lower than 3.9.14 (vulnerable versions)
  2. Check WordPress plugin admin panel
    Navigate to WP Admin > Plugins and locate Themeum Tutor LMS in the installed plugins list to view the currently active version number
    Affected if listed version is below 3.9.14
  3. Review access control implementation files
    Examine PHP files containing access control logic, particularly files in the /classes or /libraries directory that handle user authorization checks; look for code that uses $_GET, $_POST, or $_REQUEST parameters directly in permission checks without server-side validation
    Affected if code relies on user-manipulatable request parameters ($_GET, $_POST) for authorization decisions instead of validated session data

You are affected if Tutor LMS version is lower than 3.9.14 and the access control logic uses user-controllable parameters instead of server-side session validation.

Mitigation

Update Tutor LMS to version 3.9.14 or later which contains the security patch. Additionally, review and harden access control implementations to ensure all authorization decisions are based on server-side validation of authenticated sessions rather than user-controllable parameters.
