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.
-
Confirm plugin installation and versionNavigate to WordPress Admin > Plugins and locate 'Don't Muck My Markup' by Martynchamberlin. Note the installed version number.Affected if The installed version is 1.8 or lower.
-
Locate plugin PHP filesAccess the WordPress installation via file manager or FTP. Navigate to /wp-content/plugins/dont-muck-my-markup/ and list all PHP files.Affected if The plugin directory exists and contains PHP files.
-
Inspect form handling for nonce verificationOpen the main plugin PHP file(s) and search for form-related code (functions containing 'form', 'POST', 'submit'). Examine whether each form includes a nonce field (wp_nonce_field, wp_create_nonce, or similar) and whether that nonce is verified on submission (check_admin_referer, wp_verify_nonce).Affected if Forms exist that lack nonce field generation or lack nonce verification logic before processing.
-
Inspect AJAX handlers for nonce verificationSearch the plugin files for add_action calls with 'wp_ajax' or 'wp_ajax_nopriv'. Identify the callback functions for these AJAX endpoints and check whether they verify nonces using wp_verify_nonce or check_admin_referer.Affected if AJAX endpoints exist that do not verify nonces before processing requests.
-
Check for referrer validationSearch the plugin code for checks of the HTTP Referer header ( $_SERVER['HTTP_REFERER'] ) or Origin header as secondary CSRF protection.Affected if No referrer or origin header validation is implemented as defense-in-depth.
A user is affected if the plugin 'Don't Muck My Markup' version 1.8 or lower is installed and its code lacks proper nonce validation on form submissions or AJAX actions.

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 anti-CSRF tokens (nonces) on all form submissions and AJAX endpoints within the plugin, and verify these nonces on processing. Additionally, implement proper referrer header validation as a defense-in-depth measure.
