CVE-2025-40640
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 · uneditedStored Cross-Site Scripting (XSS) vulnerability in Energy CRM v2025 by Status Tracker Ltd, consisting of a stored XSS due to lack of proper validation of user input by sending a POST request to “/crm/create_invoice_submit.php”, using the “customerName_0” parameter. This vulnerability could allow a remote user to send a specially crafted query to an authenticated user and steal their cookie session details.
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 · high confidenceStored XSS vulnerability in Energy CRM v2025 allows remote attackers to inject malicious JavaScript via the customerName_0 parameter in the /crm/create_invoice_submit.php endpoint. The unsanitized input is stored and executed in authenticated users' browsers, enabling session cookie theft.

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 Energy CRM installation and versionLocate the Energy CRM installation and check version metadata (typically in about page, composer.json, or application footer). Compare against version 2025.Affected if The installed version is exactly 2025 (Energycrm Energy Crm v2025).
-
Verify create_invoice_submit.php endpoint existsCheck for the presence of the file /crm/create_invoice_submit.php in the web root or application directory.Affected if The vulnerable endpoint /crm/create_invoice_submit.php exists on the server.
-
Identify if customerName_0 parameter is processed without sanitizationReview application logs, database records, or HTTP request/response traffic for the customerName_0 parameter being accepted and stored without visible encoding or validation.Affected if The customerName_0 parameter accepts and stores raw input without input validation or output encoding.
-
Inspect stored data in database or application for unsanitized inputQuery the database (tables related to invoices or customer data) or inspect application output for the customerName_0 field to see if injected script tags or HTML are stored and rendered as-is.Affected if Raw HTML, script tags, or JavaScript event handlers appear in stored customerName_0 values and are rendered unescaped in the UI.
You are affected if Energy CRM v2025 is installed and the /crm/create_invoice_submit.php endpoint processes customerName_0 input without sanitization, allowing stored scripts to execute in authenticated users' browsers.

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 strict input validation and output encoding for the customerName_0 parameter, and configure Content-Security-Policy headers to prevent XSS execution.
