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

A Cross-Site Request Forgery (CSRF) vulnerability exists in the planetstudio Builder for Contact Form 7 WordPress plugin (versions up to 1.2.2). The plugin fails to properly validate the origin of requests, allowing attackers to trick authenticated administrators into performing unintended actions such as modifying plugin settings or submitting/altering form data.

MitigationImplement anti-CSRF tokens (nonces) on all form submissions and AJAX endpoints within the plugin, and validate the referer header or origin header on server-side operations.

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 plugin installation and version
    In WordPress admin, go to Plugins > Installed Plugins and locate 'planetstudio Builder for Contact Form 7'. Check the version number listed under the plugin name.
    Affected if The installed version is 1.2.2 or lower.
  2. Identify plugin admin AJAX handlers
    Access the plugin directory via file manager or FTP (wp-content/plugins/planetstudio-builder-cf7 or similar naming). Search for files containing 'add_action' calls with 'wp_ajax' or 'wp_ajax_nopriv' hooks.
    Affected if The plugin registers AJAX endpoints without associated nonce verification logic.
  3. Inspect form handling for nonce validation
    Examine PHP files that process form submissions (typically in main plugin file or handler classes). Look for calls to 'wp_verify_nonce', 'check_admin_referer', or 'check_ajax_referer' within functions that handle settings changes or form data submissions.
    Affected if Form processing functions lack nonce verification or only perform superficial checks without validating the request origin.
  4. Check referer header validation
    Review the same form handling code for server-side validation of '$_SERVER[HTTP_REFERER]' or '$_SERVER[HTTP_ORIGIN]' headers before processing any admin actions or form submissions.
    Affected if The plugin does not validate the referer or origin header to confirm the request originated from the expected domain.

You are affected if the planetstudio Builder for Contact Form 7 plugin version is 1.2.2 or lower and the plugin handles admin actions or form submissions without verifying nonces or validating request origins.
