CVE-2026-38939
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 Scripting vulnerability in andrewtch88 mvc-ecommerce v.1.0 allows a remote attacker to execute arbitrary code and obtain sensitive information via the product_catalogue.php component
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 Scripting (XSS) vulnerability in the product_catalogue.php component of the andrewtch88 mvc-ecommerce v1.0 application allows remote attackers to inject malicious scripts through unsanitized user input, potentially leading to arbitrary code execution in users' browsers and sensitive information disclosure.

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 mvc-ecommerce installation existsLocate the application root directory and confirm the andrewtch88 mvc-ecommerce framework is present. Look for typical e-commerce directory structure (e.g., /var/www/html, /app, or similar web root paths).Affected if The application is not installed - if not found, this CVE does not apply.
-
Confirm application versionCheck for a version file, composer.json, or README in the application root. Common locations: version.txt, README.md, or within package.json if using a JS framework. Compare the version to v1.0.Affected if Version is v1.0 - this specific version is listed as affected.
-
Locate product_catalogue.php fileSearch the application source code for the file named product_catalogue.php. Common paths in MVC frameworks: /controllers/product_catalogue.php, /views/product_catalogue.php, or /app/Http/Controllers/product_catalogue.php.Affected if File does not exist - the vulnerability cannot be present.
-
Identify user input handling in product_catalogue.phpOpen product_catalogue.php and examine the code for $_GET, $_POST, or $_REQUEST superglobals that receive user data. Look for parameters that are directly used in HTML output without sanitization functions such as htmlspecialchars, htmlentities, or similar escaping methods.Affected if User-supplied parameters are rendered in HTML output without encoding/escaping functions - the XSS vulnerability is present.
-
Test for reflected input in browserIf you have access to a test environment, navigate to the product_catalogue page and inject a benign test script tag in URL parameters (e.g., ?search=<script>alert(1)</script>). Observe whether the script executes or is reflected unescaped in the page source.Affected if The script tag executes or appears unescaped in page source - confirms active XSS vulnerability.
User is affected if they run andrewtch88 mvc-ecommerce v1.0 with the product_catalogue.php file present and user input reflected without sanitization.

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 input validation and output encoding/escaping on all user-supplied data rendered by product_catalogue.php, utilizing context-appropriate sanitization (e.g., htmlspecialchars for HTML body content) to prevent script injection.
