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 Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability and status checks on multiple functions in all versions up to, and including, 10.3.1. This makes it possible for unauthenticated attackers to view the details of unpublished, private, or password-protected quizzes, as well as submit file responses to questions from those quizzes, which allow file upload.

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 Quiz and Survey Master WordPress plugin lacks proper capability checks and status validation on multiple functions, allowing unauthenticated attackers to access unpublished, private, or password-protected quizzes and submit file uploads to those quizzes. This is a broken access control vulnerability where the plugin fails to verify quiz visibility status and user authorization before serving content or accepting submissions.

MitigationApply vendor patch when available (upgrade beyond version 10.3.1). Until then, consider restricting quiz submission endpoints via web server configuration or implementing additional access controls at the application level.

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 installed plugin version
    Access your WordPress site via FTP or file manager and navigate to /wp-content/plugins/. Look for a directory containing 'quiz' and 'survey' or 'master' in the name. Open the main PHP file and check the plugin header for 'Version:' or check readme.txt for the stable tag.
    Affected if The version displayed is lower than 10.3.2 (e.g., 10.3.1, 10.3.0, 9.x.x, etc.)
  2. Verify the plugin is active
    In WordPress admin, go to Plugins > Installed Plugins and confirm 'Quiz And Survey Master' or 'Expresstech Quiz And Survey Master' is activated.
    Affected if The plugin is active and the version is below 10.3.2
  3. Identify unpublished or private quizzes
    In WordPress admin, go to the quiz post type (usually labeled Quizzes or Surveys). Review the list to see if any quizzes have status other than 'Published' - look for Draft, Private, or Password Protected entries.
    Affected if Any quiz exists with Draft, Private, or Password Protected status while the plugin version is below 10.3.2
  4. Check if file upload is enabled on quizzes
    Edit any quiz and look for settings related to file uploads, attachments, or user submissions. Check if upload fields are available in quiz questions or quiz settings.
    Affected if File upload functionality is enabled on any quiz and the plugin version is below 10.3.2

You are affected if the Quiz And Survey Master plugin is installed with a version below 10.3.2 and you have any unpublished, private, or password-protected quizzes, especially if file upload is enabled on them.
