CVE-2026-15017
HighCVSS 8.8Summary
The MDJM Event Management plugin for WordPress up to version 1.7.8.4 contains a privilege escalation vulnerability due to missing capability checks and nonce verification in the `MDJM_Permissions::set_permissions()` and `MDJM_Employee_Manager::init()` functions, allowing unauthenticated attackers to grant arbitrary MDJM capabilities to any WordPress role and escalate to Administrator.
Risk Assessment
The risk involves privilege escalation by an unauthenticated attacker to Administrator level, potentially leading to full compromise of the WordPress site.
Recommendation
Immediately update the MDJM Event Management plugin to version 1.7.8.5 or later that fixes this vulnerability.

Original NVD description (English source)
The MDJM Event Management plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.7.8.4. This is due to missing capability checks and nonce verification in the `MDJM_Permissions::set_permissions()` and `MDJM_Employee_Manager::init()` functions, combined with the absence of server-side allow-list validation on the `employee_roles[]` and `new_role` POST parameters before they are passed to `mdjm_set_employee_role()` and `WP_User::set_role()`. This makes it possible for unauthenticated attackers to grant arbitrary MDJM capabilities — including `mdjm_employee` and `mdjm_employee_edit` — to any registered WordPress role, and subsequently leverage a subscriber-level account to escalate privileges to Administrator. `MDJM_Permissions::init()` is registered on the public WordPress `init` hook without any authentication gate, meaning the role-manipulation endpoint is reachable without any prior login.
