This is due to the AJAX actions `save_bloyal_configuration_data` and `save_bloyal_accesskeyverification_data` being registered without any capability or nonce checks, and the `bloyal_customer_auto_login` function unconditionally trusting the `Customer.ExternalId` value returned by whichever API URL is stored in the plugin's options. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the plugin's bLoyal Loyalty Engine API URL (`bloyal_custom_loyaltyengine_api_url`) and the `is_bloyal_custom_api_url` flag via the unprotected AJAX actions, then trigger the unauthenticated `/cart` REST route to cause `bloyal_customer_auto_login` to fetch customer data from an attacker-controlled endpoint and call `wp_set_auth_cookie()` with an attacker-supplied `Customer.ExternalId`, thereby authenticating as any WordPress user including the site Administrator.","published":"2026-08-15T03:16:47.393","modified":"2026-08-15T03:16:47.393","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2429"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2470"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2512"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L421"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L494"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L806"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1196"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1553"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1596"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ba4b58ad-97b3-482a-bf24-1fa85d6ef93d?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T03:16:47.393"}}
