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 · unedited
Cross Site Request Forgery (CSRF) vulnerability in Express cart v1.1.16 allows attackers to add an administrator account, add discount code or other unspecified impacts.

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 confidence

CSRF vulnerability in Express Cart v1.1.16 allows remote attackers to trick authenticated administrators into performing unauthorized administrative actions, including creating new administrator accounts and adding discount codes, by exploiting the lack of anti-CSRF tokens on state-changing operations.

MitigationImplement anti-CSRF tokens (synchronizer token pattern) on all state-changing endpoints and validate Origin/Referer headers to prevent cross-site request forgery attacks.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Express Cart is deployed
    Check for express-cart directory or look for express-cart processes. Common paths include /opt/express-cart, /var/www/express-cart, or check running node processes for express-cart.
    Affected if Express Cart application is found running or installed on the system
  2. Determine the installed Express Cart version
    Check the package.json file in the Express Cart installation directory for the 'version' field, or run 'npm list express-cart' if installed as a dependency.
    Affected if The version is 1.1.10 or lower
  3. Verify Express Cart version programmatically
    If the application is accessible, check the /protected/version endpoint or similar, or inspect the package.json shipped with the application.
    Affected if Version returned is <= 1.1.10
  4. Inspect state-changing endpoints for CSRF protection
    Review the codebase for CSRF middleware implementation. Look for 'csurf' or similar CSRF protection packages in package.json, and check if routes for admin actions (account creation, discount codes) use csrf middleware.
    Affected if No CSRF middleware is configured or state-changing admin routes lack CSRF token validation

A system is affected if it runs Express Cart version 1.1.10 or lower AND lacks anti-CSRF protection on administrative state-changing endpoints.

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.

Upgrade available Upgrade to a release after 1.1.10
Interim mitigation

Implement anti-CSRF tokens (synchronizer token pattern) on all state-changing endpoints and validate Origin/Referer headers to prevent cross-site request forgery attacks.
