NVD · unedited
Cross-Site Request Forgery (CSRF) vulnerability in ExpressTech Quiz And Survey Master – Best Quiz, Exam and Survey Plugin for WordPress plugin <= 8.0.7 versions.

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

Cross-Site Request Forgery (CSRF) vulnerability in the WordPress Quiz And Survey Master plugin versions 8.0.7 and below allows attackers to trick authenticated users into performing unintended actions (such as modifying quiz settings, creating/deleting surveys, or changing user data) via maliciously crafted requests.

MitigationImplement anti-CSRF tokens (WordPress nonces) on all state-changing operations (forms, AJAX endpoints, admin actions) and verify these nonces before processing any request.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Locate the Quiz And Survey Master plugin files
    Check the wp-content/plugins/quiz-master-next or qsm-plugin directory on your WordPress server
    Affected if The plugin directory exists on the server
  2. Identify the installed plugin version
    Open the main plugin file (usually qsm.php or quiz-master-next.php) and look for the version defined in the plugin header comment, or check the version in WordPress admin under Plugins > Installed Plugins
    Affected if The version is 8.0.7 or below (or if the version cannot be determined but the plugin is present)
  3. Verify nonce implementation in form handlers
    Inspect PHP files that handle form submissions in the plugin (commonly in includes/ or classes/ directories), looking for wp_verify_nonce or check_admin_referer calls before processing POST/GET requests that modify quiz settings, surveys, or user data
    Affected if State-changing form handlers lack nonce verification logic
  4. Check AJAX endpoints for nonce validation
    Examine AJAX action handlers registered via add_action('wp_ajax_...) and add_action('wp_ajax_nopriv_...) in the plugin, verifying that each includes nonce verification before processing requests
    Affected if AJAX endpoints that modify data do not validate nonces
  5. Review admin action hooks for CSRF protection
    Look for admin_init, admin_post_ handlers and other state-changing WordPress hooks in the plugin to confirm they verify nonces before executing operations like creating, updating, or deleting quizzes or surveys
    Affected if Admin action handlers skip nonce verification

Your environment is affected if the Quiz And Survey Master plugin is installed with version 8.0.7 or below and the plugin lacks proper nonce validation on its state-changing operations.

Generated from the published advisory. Verify against your own configuration.
