Description

The EduKart Pro plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.0.3. This is due to the 'edukart_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.

Mitigating Controls (NIST 800-53 r5)AI

AC-2 Account Management good match
prevent

AC-2 mandates processes for managing account creation, enabling, and privilege assignment during registration, directly preventing unauthenticated attackers from self-assigning administrator roles.

AC-6 Least Privilege good match
prevent

AC-6 enforces least privilege by restricting user roles and privileges to only those necessary for tasks, blocking arbitrary assignment of elevated roles like administrator during registration.

SI-10 Information Input Validation good match
prevent

SI-10 requires validation of information inputs such as the unrestricted 'role' parameter in the edukart_pro_register_user_front_end function, ensuring only permitted roles are accepted.

Security SummaryAI

CVE-2025-13559, published on 2025-11-25, is a privilege escalation vulnerability in the EduKart Pro plugin for WordPress, affecting all versions up to and including 1.0.3. The flaw exists in the 'edukart_pro_register_user_front_end' function, which does not restrict the user roles that can be specified during registration, enabling attackers to assign themselves elevated privileges.

Unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required, as reflected in its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Exploitation allows remote attackers to register a new user account with the 'administrator' role, granting full administrative access to the WordPress site and potentially leading to complete compromise (CWE-269: Improper Privilege Management).
