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 Porto Theme is installed
    Navigate to WordPress Admin > Appearance > Themes and verify that the Porto Theme (or Porto Theme - Functionality) is listed and installed
    Affected if Porto Theme is installed and active in WordPress
  2. Identify the installed version
    Check the theme version by opening wp-content/themes/porto/functions.php and locating the version defined in the theme headers, or view the theme in the WordPress themes admin panel which typically displays the version number
    Affected if The displayed version number is lower than 2.12.1
  3. Verify theme is active
    In WordPress Admin > Appearance > Themes, confirm that Porto Theme is the currently active theme (it should show as 'Active' or be applied to the live site)
    Affected if Porto Theme is the active theme on the WordPress site
  4. Check for unauthorized access indicators
    Review server access logs for unusual requests to theme-related endpoints or AJAX actions (commonly found in wp-content/themes/porto/lib or similar paths). Look for POST requests to theme files from unauthenticated or low-privilege users
    Affected if Unauthenticated or subscriber-level users are able to access theme functionality that requires higher privileges (administrator or editor)

The environment is affected if Porto Theme - Functionality is installed with a version lower than 2.12.1 and is active on the WordPress site, as this version range contains the missing authorization vulnerability.
