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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Popularis Extra theme is installedIn WordPress admin, go to Appearance > Themes and verify the Popularis Extra theme is present and activeAffected if The Popularis Extra theme is installed and activated on the WordPress site
-
Identify the installed theme versionCheck the style.css file in wp-content/themes/popularis-extra/ for the Version: header, or look in Themes panel which displays the versionAffected if The installed version falls within the affected version range for this CVE (compare your version to the affected range if known)
-
Inspect theme forms for nonce validationExamine PHP files in the theme directory for form handlers - search for 'wp_nonce_field' or 'wp_create_nonce' in template files, particularly in settings pages and user submission formsAffected if Forms and actions lack nonce verification (the code does not call wp_verify_nonce or check for a nonce token before processing)
-
Check AJAX handlers for nonce protectionSearch theme PHP files for 'add_action' with 'wp_ajax' and verify each handler calls 'check_ajax_referer' or 'wp_verify_nonce' before processingAffected if AJAX endpoints registered by the theme do not validate nonces (no nonce check before executing the action)
-
Review admin actions for CSRF protectionLocate admin menu creation (add_menu_page, add_submenu_page) and associated handler functions - verify they include nonce validation before any state-changing operationsAffected if Admin actions triggered by the theme lack anti-CSRF token validation
A user is affected if the Popularis Extra theme is installed without proper nonce validation on its forms, AJAX handlers, and admin actions, allowing authenticated users to be tricked into performing unintended actions via malicious links.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement WordPress nonces (anti-CSRF tokens) on all forms and AJAX actions, and validate the nonce on the server side before processing requests.
