CVE-2026-3318
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 · uneditedOpen redirection vulnerability in the latest demo version of the Cradle eCommerce platform. The vulnerability occurs in the login form endpoint, where the ‘returnUrl’ parameter allows redirection because the web application accepts a URL as a parameter without properly validating it. As a result, it is possible to redirect users from the legitimate website to external pages. An attacker could exploit this vulnerability to deceive users and redirect them from a trusted URL to a malicious one without their knowledge.

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 if Cradle eCommerce platform is in useCheck web application fingerprints, headers, or source code for 'Cradle' or 'cradle-ecommerce' identifiers. Inspect the application's about page, footer, or meta tags for the product name.Affected if The system runs the Cradle eCommerce platform software.
-
Locate the login form endpointIdentify the login page URL in the application. Common paths include /login, /account/login, /user/signin, or similar authentication endpoints. Check the HTML form action attribute.Affected if A login form endpoint exists and is accessible.
-
Inspect the returnUrl parameter handlingSubmit a test request to the login form with a known external URL as the returnUrl parameter (e.g., returnUrl=http://example.com). Examine the application's response and the Location header in the redirect to see if the external URL is accepted and used verbatim.Affected if The application accepts and redirects to arbitrary external URLs in the returnUrl parameter without validation.
-
Verify redirect behaviorAfter authentication, observe whether the application redirects to the URL specified in returnUrl. Capture the HTTP response headers and verify if the Location header contains the unvalidated external URL.Affected if The application performs a redirect to the attacker-controlled URL after login.
If the system runs Cradle eCommerce and the login endpoint accepts arbitrary external URLs via the returnUrl parameter without validation, the environment is affected by this open redirection 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 strict validation of the returnUrl parameter to only allow relative paths or a whitelist of trusted domains; reject or sanitize any external URLs before performing the redirect.
