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 aerin Loan Repayment Calculator and Application Form.This issue affects Loan Repayment Calculator and Application Form: from n/a through 2.9.4.
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 confidenceA CSRF vulnerability exists in the aerin Loan Repayment Calculator and Application Form WordPress plugin (versions up to 2.9.4). The plugin fails to implement proper anti-CSRF tokens on form submissions, allowing attackers to trick authenticated users into performing unintended actions such as submitting fraudulent loan applications or modifying repayment data.

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.
-
Verify plugin installation and versionCheck the WordPress plugins directory or use wp-cli: 'wp plugin list --plugin=aerin-loan-repayment-calculator' or inspect the plugin header in the main plugin file for the Version fieldAffected if The plugin is installed and the reported version is 2.9.4 or lower
-
Identify form handler endpointsInspect the plugin files for form action attributes and identify which PHP files handle form submissions (look for $_POST or $_REQUEST processing related to loan applications or repayment data)Affected if The plugin contains form handlers that process submissions without explicit mention of nonce verification
-
Inspect form handler code for nonce implementationOpen the identified form handler PHP files and search for 'wp_verify_nonce', 'check_admin_referer', 'check_ajax_referer', or 'nonce' verification logic within the submission handling codeAffected if No nonce verification functions are found in the form submission handling code, or the nonce field is missing from the plugin's form templates
-
Check form templates for nonce fieldsLocate the plugin's form template files (typically .php or .html files containing form elements) and search for '<input type="hidden" name="_wpnonce"' or similar nonce field implementationsAffected if The forms lack nonce token hidden fields in their markup
A user is affected if the aerin Loan Repayment Calculator plugin version 2.9.4 or lower is installed AND the form submission handlers lack WordPress nonce verification logic.

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 nonces on all form endpoints and verify nonce validity on form submission handlers. Additionally, add SameSite attribute to session cookies and validate Referer/Origin headers.
