CVE-2023-46495
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 EverShop NPM versions before v.1.0.0-rc.8 allows a remote attacker to obtain sensitive information via a crafted request to the sortBy parameter.
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 sortBy parameter of EverShop e-commerce platform versions prior to v1.0.0-rc-8. An unauthenticated remote attacker can inject malicious JavaScript code through the crafted sortBy parameter in an HTTP request, which gets reflected back in the response without proper sanitization, potentially allowing session hijacking or sensitive data exfiltration.

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 EverShop installationIdentify whether the EverShop e-commerce platform is deployed in your environment. Check for EverShop-specific directories, configurations, or running processes.Affected if EverShop is present in the environment
-
Check installed EverShop versionLocate the version file or package.json in your EverShop installation. Run: npm list evershop or check package.json version field. Compare against affected range: versions prior to v1.0.0-rc-8 (specifically 1.0.0).Affected if Installed version is 1.0.0 or any version prior to 1.0.0-rc-8
-
Verify sortBy parameter is accessibleDetermine if product listing or catalog pages using the sortBy parameter are accessible on your site. This parameter typically appears on category/product listing pages with sorting options.Affected if SortBy parameter functionality is enabled and accessible on storefront pages
-
Test sortBy parameter for XSS reflectionSend a crafted HTTP request with a test XSS payload in the sortBy parameter, such as: ?sortBy=<script>alert(1)</script> and observe if the payload is reflected unescaped in the response HTML.Affected if The sortBy parameter reflects input without proper encoding or sanitization in the HTTP response
Your environment is affected if EverShop version 1.0.0 or any version prior to 1.0.0-rc-8 is installed AND the sortBy parameter on product listing pages reflects unsanitized input in responses.

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.
dbcve · scopedUpgrade EverShop to version 1.0.0-rc-8 or later which contains the security fix for this XSS vulnerability.
v.1.0.0-rc.8 or later
- Check the current EverShop version in package.json
- Update the EverShop dependency to version 1.0.0-rc.8 or later by running: npm install @evershop/[email protected] (or latest stable version)
- Run npm install to update all dependencies
- Test the application to verify the sortBy parameter is properly sanitized
