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
Missing Authorization vulnerability in Tobias CF7 WOW Styler allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects CF7 WOW Styler: from n/a through 1.7.6.

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 in the CF7 WOW Styler WordPress plugin allows authenticated attackers to access functionality they shouldn't have access to due to incorrectly configured access control security levels. This is likely an Insecure Direct Object Reference (IDOR) or missing capability checks in the plugin's admin AJAX handlers.

MitigationImplement proper authorization checks and capability verification (current_user_can) for all sensitive operations in the plugin, ensuring users have appropriate permissions before allowing access to styler 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 CF7 WOW Styler plugin presence
    Navigate to WordPress admin dashboard > Plugins and locate CF7 WOW Styler in the list of installed plugins
    Affected if The plugin is installed and active in the WordPress environment
  2. Identify installed plugin version
    In the Plugins page, click on the plugin to view its details and version number, or read the version from the plugin header file in wp-content/plugins/cf7-wow-styler
    Affected if The installed version has not been patched for missing authorization checks
  3. Test AJAX endpoint accessibility
    Inspect network requests or use a tool to send direct requests to admin-ajax.php with cf7_wow_styler related actions without valid authentication credentials
    Affected if The AJAX endpoints respond successfully without requiring proper user authentication or capability verification
  4. Inspect code for capability checks
    Examine the plugin PHP files for presence of current_user_can() function calls before executing sensitive operations
    Affected if Sensitive functions lack current_user_can() verification or the checks are improperly implemented
  5. Check for nonce validation
    Review plugin PHP code for wp_verify_nonce, check_admin_referer, or similar nonce validation functions on AJAX handlers and form processing
    Affected if Sensitive actions lack proper nonce validation or the validation is missing entirely

A user is affected if the CF7 WOW Styler plugin is installed and its sensitive endpoints/functions are accessible without proper WordPress capability checks and nonce validation.
