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
Deserialization of Untrusted Data vulnerability in Brainstorm Force CartFlows cartflows allows Object Injection.This issue affects CartFlows: from n/a through <= 2.1.19.

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 confidence

A PHP Object Injection vulnerability exists in the CartFlows WordPress plugin stemming from unsafe use of unserialize() on untrusted data. This allows authenticated attackers (depending on plugin configuration) to instantiate arbitrary PHP objects, potentially leading to code execution via POP chain gadget manipulation.

MitigationUpdate CartFlows plugin to version greater than 2.1.19; if immediate update is not feasible, disable the plugin until patched.

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. Verify CartFlows plugin is installed
    Access WordPress admin dashboard and navigate to Plugins > Installed Plugins, or check for /wp-content/plugins/cartflows/ directory on the server file system
    Affected if CartFlows plugin appears in the list of installed plugins or the directory exists on the server
  2. Check installed CartFlows version
    In WordPress admin, go to Plugins > Installed Plugins and locate CartFlows to view the version number, or open /wp-content/plugins/cartflows/readme.txt and locate the version in the header section
    Affected if The version number is 2.1.19 or lower
  3. Determine if user registration is enabled
    In WordPress admin, go to Settings > General and check 'Membership: Anyone can register' is checked, or inspect the site_options database table for the 'users_can_register' option value
    Affected if User registration is enabled and the site allows new user signups
  4. Confirm WordPress user roles exist
    In WordPress admin, navigate to Users > All Users to list registered accounts, or query the wp_users and wp_usermeta database tables
    Affected if There are existing registered users beyond the administrator account

Your environment is affected if CartFlows plugin versions 2.1.19 or lower are installed, user registration is enabled, and you have authenticated user accounts present.

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.
