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.

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

Cross-Site Request Forgery (CSRF) vulnerability in the Popularis Extra WordPress theme allows attackers to induce authenticated users to perform unintended actions by tricking them into visiting malicious links or pages.

MitigationImplement WordPress nonces (anti-CSRF tokens) on all forms and AJAX actions, and validate the nonce on the server side before processing requests.

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 Popularis Extra theme is installed
    In WordPress admin, go to Appearance > Themes and verify the Popularis Extra theme is present and active
    Affected if The Popularis Extra theme is installed and activated on the WordPress site
  2. Identify the installed theme version
    Check the style.css file in wp-content/themes/popularis-extra/ for the Version: header, or look in Themes panel which displays the version
    Affected if The installed version falls within the affected version range for this CVE (compare your version to the affected range if known)
  3. Inspect theme forms for nonce validation
    Examine 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 forms
    Affected if Forms and actions lack nonce verification (the code does not call wp_verify_nonce or check for a nonce token before processing)
  4. Check AJAX handlers for nonce protection
    Search theme PHP files for 'add_action' with 'wp_ajax' and verify each handler calls 'check_ajax_referer' or 'wp_verify_nonce' before processing
    Affected if AJAX endpoints registered by the theme do not validate nonces (no nonce check before executing the action)
  5. Review admin actions for CSRF protection
    Locate admin menu creation (add_menu_page, add_submenu_page) and associated handler functions - verify they include nonce validation before any state-changing operations
    Affected 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.
