No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
