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 installationCheck if the plugin 'Accept PayPal Payments using Contact Form 7' exists in your WordPress installation by looking in the wp-content/plugins/ directory for a folder named similarly to 'contact-form-7-paypal-add-on' or 'cf7-paypal'. You can also check via WordPress admin under Plugins > Installed Plugins.Affected if The plugin is installed and active in WordPress
-
Identify installed plugin versionOpen the main plugin file (usually named like plugin-name.php) and locate the version comment or header. Compare this version against any officially released patches or the plugin developer's security advisories.Affected if The installed version has not been patched for missing authorization checks
-
Inspect admin pages for capability checksExamine the plugin's PHP files for admin-related functions and pages. Look for the presence of capability checks such as 'current_user_can()' or 'admin_url()' verification before executing sensitive operations like saving settings, processing payments, or modifying configuration.Affected if Sensitive admin functions lack proper capability verification (e.g., no current_user_can('manage_options') call before critical actions)
-
Verify nonce validation on form submissionsSearch the plugin code for form handling functions that process PayPal payments or configuration changes. Check if these functions include nonce verification using wp_verify_nonce() or check_admin_referer() before processing requests.Affected if Form processing functions accept requests without validating nonces, allowing forged requests from authorized users
You are affected if the plugin is installed and its version lacks the authorization and nonce validation fixes that properly enforce capability checks on sensitive functions.

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 dataUpdate the plugin to the latest version once available, which should include proper capability checks, nonce verification, and role-based access controls for all sensitive operations.
