AI Threat Summary

CVE-2026-105894 is a high-severity vulnerability with a CVSS score of 8.8 affecting the target software. Authentication can be bypassed allowing unauthenticated access. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.

Description

The Ak Framework plugin for WordPress, included in the Newsy - Viral News & Magazine WordPress Theme, is vulnerable to Privilege Escalation in all versions up to, and including, 2.9.8. This is due to missing capability checks in the ajax_refresh_nonce and ak_admin_ajax handlers before passing attacker-controlled option names and values to update_option(). This makes it possible for unauthenticated attackers to update arbitrary WordPress options including users_can_register and default_role to escalate privileges to administrator by enabling user registration with administrator as the default role.
