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."}],"title":"bLoyal: Loyalty & Promotions by bLoyal <= 3.1.611.78 - Authenticated (Subscriber+) Privilege Escalation via Unprotected AJAX API URL Settings","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ba4b58ad-97b3-482a-bf24-1fa85d6ef93d?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L421"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2470"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2429"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1553"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1596"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L494"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1196"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2512"},{"url":"https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L806"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"CHOIGYEONGMIN"}],"timeline":[{"time":"2026-08-14T14:02:02.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-17T15:14:03.889182Z","id":"CVE-2026-15001","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-17T16:07:29.548Z"}}]}}
