Official Description

The Welcome Software Publishing plugin for WordPress is vulnerable to Arbitrary Options Update in all versions up to and including 0.0.31. This is due to a missing capability check in the nc_setOption() function, which is exposed via the nc.setOption XML-RPC method. The function authenticates the user via $wp_xmlrpc_server->login() (verifying credentials are valid) but does not perform any authorization check such as current_user_can('manage_options'). This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary WordPress options via XML-RPC requests. This can be leveraged to change the default_role option to 'administrator' and then register a new administrator account, achieving full privilege escalation and site takeover.

Technical Analysis

CVE-2026-4297 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
