Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-6 Least Privilege good match

prevent

Enforces least privilege to prevent assignment of administrator roles during unauthenticated user registration.

AC-2 Account Management good match

prevent

Manages account creation processes to restrict self-registration to authorized roles only, blocking arbitrary role specification.

SI-10 Information Input Validation good match

prevent

Validates user-supplied role inputs in the registration function to reject unauthorized roles like administrator.

Why these techniques?

The vulnerability is a privilege escalation in a public-facing WordPress plugin, allowing unauthenticated attackers to gain administrator access, directly enabling T1068 (Exploitation for Privilege Escalation) and T1190 (Exploit Public-Facing Application).

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

The Lizza LMS Pro plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.0.3. This is due to the 'lizza_lms_pro_register_user_front_end' function not restricting what user roles a user can register with. This makes it…

possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site.

Deeper analysisAI

CVE-2025-13563 is a privilege escalation vulnerability in the Lizza LMS Pro plugin for WordPress, affecting all versions up to and including 1.0.3. The flaw arises in the 'lizza_lms_pro_register_user_front_end' function, which does not restrict the user roles that can be assigned during front-end registration, allowing arbitrary role specification.

Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no privileges or user interaction required. By supplying the 'administrator' role during registration, they gain full administrator access to the site, enabling high-impact confidentiality, integrity, and availability violations, as reflected in the CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and mapped to CWE-269 (Improper Privilege Management).

Advisories from Wordfence detail the issue and recommend mitigation. Security practitioners should consult the Wordfence threat intelligence report and the plugin's ThemeForest page for patching guidance, with updates to versions beyond 1.0.3 addressing the vulnerability where available.
