CVE-2013-7476
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.
NVD · uneditedThe simple-fields plugin before 1.2 for WordPress has CSRF in the admin interface.
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 confidenceThe simple-fields WordPress plugin before version 1.2 contains a Cross-Site Request Forgery (CSRF) vulnerability in its admin interface. This allows attackers to trick authenticated administrators into performing unintended actions via malicious requests, as the plugin fails to validate anti-CSRF tokens on admin operations.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Locate the simple-fields plugin installationCheck the WordPress plugins directory at wp-content/plugins/ for a folder named 'simple-fields' or similar. Also check wp-content/mu-plugins/ if present.Affected if The simple-fields plugin folder exists in the WordPress installation.
-
Identify the installed plugin versionOpen the main plugin file (usually simple-fields.php) and look for the version header in the plugin comment block, or check the readme.txt file for the 'Stable tag' entry.Affected if The version number found is less than 1.2 (e.g., 1.1.x, 1.0.x, or no version specified).
-
Verify the plugin is activeLog into the WordPress admin dashboard, go to Plugins > Installed Plugins, and check whether the simple-fields plugin is currently activated.Affected if The simple-fields plugin shows as 'Active' in the WordPress admin plugins list.
-
Inspect admin forms for nonce field absenceIn the plugin PHP files (typically in the /inc/ or /classes/ folder within simple-fields), search for admin form definitions (HTML <form> tags) and check if they include a nonce field (wp_nonce_field, wp_nonce_url, or similar).Affected if Admin forms in the plugin code lack any wp_nonce_field or equivalent CSRF token generation calls.
-
Inspect AJAX handlers for nonce verificationSearch the plugin PHP files for AJAX action handlers (add_action with 'wp_ajax_' or 'wp_ajax_nopriv_' hooks) and check if these handlers verify nonces using check_ajax_referer or wp_verify_nonce.Affected if AJAX endpoints registered by the plugin do not call check_ajax_referer or wp_verify_nonce to validate CSRF tokens.
You are affected if the simple-fields plugin is installed, active, and its version is below 1.2, with admin forms and AJAX handlers lacking CSRF token validation.

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 data1.2
Update the simple-fields plugin to version 1.2 or later which includes CSRF protection. Alternatively, add WordPress nonces to all admin forms and AJAX endpoints, and verify these nonces on form submission.
