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 – eLearning and online course solution plugin for WordPress is vulnerable to time-based SQL Injection via the question_id parameter in all versions up to, and including, 2.6.1 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/student access or higher, 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 WordPress plugin versions up to 2.6.1 contain a time-based SQL injection vulnerability in the question_id parameter. Authenticated users with subscriber/student access can inject malicious SQL queries due to insufficient escaping and lack of prepared statements in the existing SQL query, allowing extraction of sensitive database information.

MitigationUpdate Tutor LMS to version 2.6.2 or later. If immediate update is not possible, implement input validation on the question_id parameter and refactor vulnerable queries to use WordPress $wpdb->prepare() prepared statements.

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 is installed and active
    Log into WordPress admin and navigate to Plugins > Installed Plugins, or use WP-CLI: wp plugin list --status=active --filter=name=tutor
    Affected if Tutor LMS plugin is installed and active on the WordPress site
  2. Check installed Tutor LMS version
    In WordPress admin, go to Plugins > Installed Plugins and find Tutor LMS to view the version number, or check the plugin header in wp-content/plugins/tutor/ VERSION file or main plugin PHP file
    Affected if The installed version is 2.6.1 or lower (any version below 2.6.2)
  3. Confirm low-privilege user roles can access quiz question functionality
    Review WordPress user roles and capabilities. Check if subscriber or student role exists and has access to quiz/assignment features. Navigate to Users > All Users in WP admin to see existing roles, or inspect the tutor plugin capability settings
    Affected if Subscriber or student roles exist and are permitted to access quiz question review features where question_id parameter is used

If Tutor LMS version is below 2.6.2 AND low-privilege authenticated users (subscriber/student) can access the question_id parameter in quiz functionality, the site is vulnerable to SQL injection.
