NVD · unedited

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 Mihdan: No External Links WordPress plugin. The plugin fails to properly validate anti-CSRF tokens, allowing authenticated users to be tricked into performing unintended state-changing actions via malicious requests.

MitigationImplement WordPress nonce verification (wp_verify_nonce or wp_nonce_field) on all state-changing operations (settings updates, form submissions, admin actions) to prevent CSRF attacks.

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. Verify plugin is installed and active
    Go to WordPress admin > Plugins and confirm 'Mihdan: No External Links' is installed and activated
    Affected if The plugin is installed and active on the WordPress site
  2. Check installed plugin version
    In WordPress admin > Plugins, find Mihdan: No External Links and note the version number displayed. Compare against any officially published affected version range
    Affected if The installed version falls within a known vulnerable version range (if such a range becomes publicly documented)
  3. Inspect plugin code for nonce validation
    Access the plugin files via file manager or FTP. Examine PHP files that handle form submissions, settings saves, and admin actions (typically in the main plugin file or includes/admin/). Search for presence of wp_verify_nonce, wp_nonce_field, or check_admin_referer calls on state-changing functions
    Affected if State-changing operations (settings updates, form submissions, admin actions) lack nonce verification calls like wp_verify_nonce or wp_nonce_field
  4. Check admin action handlers for CSRF protection
    Locate PHP files handling admin actions (often containing add_action hooks like admin_post_, wp_ajax_, or admin_menu). Verify each handler that modifies data calls wp_verify_nonce or check_admin_referer before processing
    Affected if Admin action handlers that modify data do not validate nonces before executing state-changing operations

A site is affected if the Mihdan: No External Links plugin is active and its code lacks proper nonce verification (wp_verify_nonce or similar) on state-changing operations like settings updates or form submissions.
