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

Missing authorization vulnerability in the Questionar for Elementor WordPress plugin allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before granting access to sensitive functionality or data, likely through AJAX endpoints or front-end functions that should require administrative privileges. This enables lower-privileged users or unauthenticated attackers to access capabilities they should not have.

MitigationUpdate to the latest version of Questionar for Elementor if available; otherwise, implement proper capability checks (e.g., current_user_can()) on all AJAX handlers and sensitive functions, and restrict access to admin-only functionality.

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. Confirm Questionar for Elementor plugin is installed
    Navigate to WordPress Admin > Plugins and verify Questionar for Elementor is listed, or check /wp-content/plugins/ directory for the plugin folder
    Affected if The plugin is installed and active
  2. Identify the installed plugin version
    In WordPress Admin > Plugins, click on the plugin name to view details, or read the main plugin PHP file for the Version header comment
    Affected if The installed version predates the patched version
  3. Inspect AJAX handlers for missing capability checks
    Search plugin PHP files for add_action('wp_ajax_') calls and verify each handler includes current_user_can() or similar authorization checks at the very beginning of the function
    Affected if AJAX endpoints exist without current_user_can() validation at the start of their handler functions
  4. Check front-end functions for authorization bypass
    Review plugin PHP files for public-facing functions that perform sensitive operations and verify they enforce proper user capability checks
    Affected if Sensitive functionality can be accessed by lower-privileged users or unauthenticated visitors without proper permission validation

The environment is affected if the Questionar for Elementor plugin is installed and its AJAX handlers or sensitive functions lack proper authorization checks, allowing access by users without adequate privileges
