# CVE-2026-6020

## Summary

- **CVE ID:** CVE-2026-6020
- **Severity:** HIGH
- **CVSS Score:** 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)
- **CWE:** CWE-470
- **Published:** Aug 5, 2026
- **Last Modified:** Aug 5, 2026

## Description

The ShopLentor plugin for WordPress is vulnerable to arbitrary function execution via the woolentoropt/v1/custom-action REST API endpoint in all versions up to, and including, 3.3.7. This is due to the handle_action() method passing user-supplied input directly to call_user_func() without an allowlist of permitted callbacks. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary PHP callable functions via the 'callback' parameter.
