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 time-based SQL Injection via the ‘is_linking’ parameter in all versions up to, and including, 10.3.1 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-level access 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 Quiz and Survey Master WordPress plugin fails to properly escape the user-supplied 'is_linking' parameter and lacks sufficient prepared statements in its SQL queries. This allows authenticated attackers with Subscriber-level permissions to inject time-based SQL queries (using functions like SLEEP()) to extract sensitive data from the database.

MitigationUpdate to version 10.3.2 or later when released. Until then, remove Subscriber-level permissions from untrusted users or temporarily disable the plugin.

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 Quiz and Survey Master plugin is installed
    Navigate to WordPress Admin > Plugins and locate 'Quiz and Survey Master' or 'Expresstech Quiz And Survey Master' in the installed plugins list
    Affected if Plugin is not found in the installed plugins list, then the plugin is not present and this CVE does not apply
  2. Determine the installed plugin version
    In WordPress Admin > Plugins, click on the plugin name to view its details, or check the plugin header in /wp-content/plugins/quiz-master-next/ folder for the 'Version' field
    Affected if The version number displayed is lower than 10.3.2 (e.g., 10.3.1, 10.3.0, 9.x.x, etc.)
  3. Confirm the plugin is active
    In WordPress Admin > Plugins > Installed Plugins, verify that Quiz and Survey Master shows as 'Active' under the plugin status
    Affected if Plugin is active and version is below 10.3.2, indicating the vulnerable code is running
  4. Check for subscriber-level or low-privilege user accounts
    In WordPress Admin > Users, review the list of registered users. Check the 'Role' column for accounts with 'Subscriber' role or any custom role with low permissions
    Affected if Any user with Subscriber-level permissions or lower exists on the site, and the plugin is active and vulnerable, an authenticated attacker could exploit the SQL injection

If the Quiz and Survey Master plugin is active at a version lower than 10.3.2 AND any subscriber-level or low-privilege user account exists on the WordPress site, the environment is affected by this SQL injection vulnerability.
