The Eazy Plugin Manager – Powerful Plugin Management Solution for WordPress plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.4.1. This is due to insufficient authorization on the `wp_ajax_pos_get_option` AJAX handler, which verifies only a nonce that is localized to every logged-in admin-area user via `admin_enqueue_scripts` — without any capability check — before returning the value of any arbitrary WordPress option via `get_option()`, combined with the `admin_login_endpoint_handler` REST endpoint (`GET /wp-json/epm/v1/admin/login`) being registered as publicly accessible and authenticating callers solely by a whirlpool hash of values stored in those same options. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the `site_url`, `connection_key`, and `remote_user_id` values stored in the `eazywp_connecting_info` and `eazywp_connection` options, compute the required `auth_key`, call the `admin/login` REST endpoint to obtain Administrator authentication cookies, and fully take over the site. Exploitation requires the plugin's remote connection feature to have been configured, as the `eazywp_connecting_info` and `eazywp_connection` options must be populated with valid credentials.

The advisory is shared at wordfence.com. This vulnerability is known as CVE-2026-14328 since 07/01/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/28/2026).
