Executive Summary

CVE-2026-39477 is a broken access control vulnerability in the WordPress CartFlows plugin versions up to and including 2.2.3.

This issue arises from missing authorization, authentication, or nonce token checks within certain plugin functions, allowing unprivileged users (such as contributors or developers) to perform actions that require higher privileges.

It is classified under the OWASP Top 10 category A1: Broken Access Control.

Impact Analysis

This vulnerability allows unprivileged users to perform actions that should require higher privileges, potentially leading to unauthorized changes or access within the affected WordPress site.

Although the CVSS severity score is 4.3, indicating a low severity impact, the vulnerability can be exploited in mass campaigns targeting many websites indiscriminately.

It does not pose a significant threat specifically to high-traffic or popular sites but should be addressed promptly to prevent exploitation.

Users are strongly advised to update to version 2.2.4 or later to mitigate the risk.

Detection Guidance

This vulnerability is related to missing authorization checks in the WordPress CartFlows plugin versions up to 2.2.3. Detection typically involves verifying the plugin version installed on your WordPress site.

You can check the installed version of the CartFlows plugin by running commands on your server or using WordPress CLI tools.

  • Using WP-CLI: wp plugin list | grep cartflows
  • Manually check the plugin version in the WordPress admin dashboard under Plugins.

There are no specific network detection commands or signatures provided for this vulnerability in the available resources.

Mitigation Strategies

The primary mitigation step is to update the CartFlows plugin to version 2.2.4 or later, where the vulnerability has been patched.

Additionally, enabling auto-updates for the plugin can provide rapid protection against this and similar vulnerabilities.
