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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in SaifuMak Add Custom Codes add-custom-codes allows Cross Site Request Forgery.This issue affects Add Custom Codes: from n/a through <= 4.80.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in the SaifuMak Add Custom Codes WordPress plugin allows attackers to trick authenticated administrators into executing unintended actions like adding malicious custom code through crafted requests, since the plugin lacks proper anti-CSRF token validation on state-changing 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 checksWork through these to decide whether this CVE applies to you.
-
Locate the SaifuMak Add Custom Codes pluginCheck for the plugin directory in wp-content/plugins/, typically named 'saifumak-add-custom-codes' or similar, and list its files.Affected if The plugin directory exists in the WordPress installation.
-
Identify the installed versionOpen the main plugin PHP file (usually named plugin-name.php or index.php) and look for the 'Version' header in the plugin comment block at the top of the file.Affected if No fixed version is known from the CVE; compare the found version against any future patched releases.
-
Inspect AJAX action handlers for nonce validationSearch the plugin PHP files for registered AJAX hooks (add_action with 'wp_ajax_') and check if they call wp_verify_nonce or check_admin_referer before processing the request.Affected if AJAX handlers exist but do not verify nonces, meaning forged requests can be executed.
-
Inspect form handlers for nonce validationSearch the plugin PHP files for form processing code and check if nonces are included in forms (wp_nonce_field) and verified (wp_verify_nonce) before any state-changing operations.Affected if Forms perform database writes or settings changes without nonce verification.
-
Check for Origin or Referer header validationSearch the plugin PHP files for $_SERVER['HTTP_ORIGIN'] or $_SERVER['HTTP_REFERER'] checks that validate request origins.Affected if No origin validation exists, allowing requests from malicious sites to be processed.
The user is affected if the SaifuMak Add Custom Codes plugin is installed and its AJAX handlers, form handlers, or state-changing operations lack wp_verify_nonce or check_admin_referer calls.

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 nonce verification on all forms and AJAX actions within the plugin, and validate Origin/Referer headers to ensure requests originate from legitimate sources.
