What is CVE-2026-6020?

The ShopLentor plugin for WordPress contains a vulnerability that allows authenticated users with Administrator-level access to execute arbitrary PHP callable functions. This is due to the 'handle_action()' method directly passing user-supplied input to 'call_user_func()' without proper validation. Attackers can exploit this through the 'callback' parameter in the woolentoropt/v1/custom-action REST API endpoint, posing a serious threat to the integrity of the WordPress site.

Affected Version(s)
