Motorix PHP Object Injection

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-62004

The vulnerability affects a WordPress theme (Motorix). WordPress themes are deployed as part of public-facing web applications. Because these applications are designed to be accessible over the internet to serve content and functionality, the vulnerable code is commonly exposed to the public internet.

Frequently asked questions

What is Motorix?

Motorix is a WordPress theme. WordPress themes control the visual design and layout of a website. They include PHP files that interact with the WordPress core and other plugins to display content to visitors.

What does PHP Object Injection mean in CVE-2026-62004?

This is a vulnerability class, known as CWE-502, where an application improperly handles serialized data. An attacker can inject malicious objects into the application's memory, which the PHP engine then processes as legitimate code, often leading to unauthorized system control.

How is this vulnerability triggered?

An attacker triggers this by sending specifically formatted, malicious input to the web application. The vulnerability does not trigger through normal user browsing; it requires the attacker to bypass standard input validation to reach the vulnerable theme code.

Do I need to worry if my Motorix site is on the internet?

Yes. According to Halo Surface Signal, because Motorix is a WordPress theme designed to serve public content, it is almost certainly exposed to the internet. This accessibility increases the likelihood that a remote, unauthenticated attacker could target your site.

How should I respond to this vulnerability?

Start by identifying all servers running the Motorix theme. Once you have a list, work with your web administration or application team to confirm if the theme is active, evaluate its business impact, and prepare to update or replace it during your next scheduled maintenance.
