{"id":"CVE-2026-15001","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-15001","generatedAt":"2026-10-28T09:26:55.073Z","title":"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.","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.","published":"2026-08-15T03:16:47.000Z","lastModified":"2026-08-20T12:48:10.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","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"},"cwe":["CWE-269"],"affected":[],"epss":{"score":0.00689,"percentile":0.52572,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.69%).
