{"id":"CVE-2026-15001","state":"PUBLISHED","title":"bLoyal: Loyalty & Promotions by bLoyal <= 3.1.611.78 - Authenticated (Subscriber+) Privilege Escalation via Unprotected AJAX API URL Settings","description":"The bLoyal: Loyalty & Promotions by bLoyal plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.1.611.78. 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.","publishedAt":"2026-08-15T02:26:17.515Z","updatedAt":"2026-08-17T16:07:29.548Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["connectordev bLoyal: Loyalty & Promotions by bLoyal"],"affected":[{"vendor":"connectordev","product":"bLoyal: Loyalty & Promotions by bLoyal","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1.611.78","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ba4b58ad-97b3-482a-bf24-1fa85d6ef93d?source=cve","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L421","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2470","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2429","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1553","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1596","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L494","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/bloyal.php#L1196","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L2512","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L806"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15001.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15001","state":"PUBLISHED","datePublished":"2026-08-15T02:26:17.515Z","dateUpdated":"2026-08-17T16:07:29.548Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-07T19:53:43.978Z"},"containers":{"cna":{"title":"bLoyal: Loyalty & Promotions by bLoyal <= 3.1.611.78 - Authenticated (Subscriber+) Privilege Escalation via Unprotected AJAX API URL Settings","descriptions":[{"lang":"en","value":"The bLoyal: Loyalty & Promotions by bLoyal plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.1.611.78.
