CVE-2026-3320
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 · uneditedReflected Cross-Site Scripting (XSS) in the latest demo version of the Cradle eCommerce platform. User-controlled input is insecurely reflected in the HTML output in the endpoint /product/. Exploitation of this vulnerability would allow an attacker to execute arbitrary JavaScript code.
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 confidenceA reflected Cross-Site Scripting (XSS) vulnerability exists in the Cradle eCommerce platform demo at the /product/ endpoint. User-supplied input is directly reflected into the HTML output without proper sanitization or encoding, allowing an attacker to inject malicious JavaScript code that executes in victim browsers.

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.
-
Identify Cradle eCommerce platformInspect the application banner, check the footer, or review the source code for 'Cradle' or 'ecommerce' branding to confirm the platform is in useAffected if The application is running the Cradle eCommerce platform demo or software
-
Locate the /product/ endpointAccess the /product/ endpoint in the web browser or via a tool like curl (e.g., curl -s https://target/product/)Affected if The /product/ endpoint exists and returns a page with user-supplied input reflected in the response
-
Test for reflected inputAppend a test parameter to the /product/ URL (e.g., /product/?id=<script>alert(1)</script>) and examine the HTTP response body to see if the raw script tags appear unencodedAffected if The injected script tags or other HTML characters are returned verbatim in the HTML response without encoding
-
Verify lack of output encodingSearch the page source or raw HTTP response for the literal string '<script>' or other user-supplied input appearing unescapedAffected if User-controlled input is reflected directly into the HTML output without HTML entity encoding (e.g., < instead of <)
-
Confirm XSS execution potentialUse a browser to visit the crafted URL and check if a JavaScript alert or other script execution occursAffected if The malicious payload executes in the browser, demonstrating the XSS vulnerability is present and exploitable
If the Cradle eCommerce platform is running and the /product/ endpoint reflects user input without HTML encoding, the environment is affected by this XSS vulnerability.

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 context-appropriate output encoding or use a sanitization library to neutralize malicious input before reflecting it in HTML. Additionally, configure Content Security Policy (CSP) headers to mitigate XSS impact.
