{"cve":"CVE-2026-15001","nvd":{"published":"2026-08-15T03:16:47.393","modified":"2026-08-20T12:48:10.287","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["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/app/controller/class-bloyalcontroller.php#L2470","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#L421","https://plugins.trac.wordpress.org/browser/bloyal/tags/3.1.611.78/app/controller/class-bloyalcontroller.php#L494"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-15001","score":0.00689,"percentile":0.52789,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
