# Gamezone WordPress theme: unauthenticated PHP object injection lets attackers run code

Gamezone versions 1.1.11 and earlier accept untrusted serialized PHP data, which lets an unauthenticated visitor inject PHP objects. A successful attacker can often turn that into code execution on the server, though the sources do not detail the exact gadget chain.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Gamezone version in the theme's style.css header or the Appearance > Themes screen, and compare it with `1.1.11`

## Fix

- Gamezone versions after `1.1.11` (exact fixed version not stated in the sources)

## Timeline

- 2026-10-29T16:26:00+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-62015

## From the sources

Unauthenticated PHP Object Injection in Gamezone <= 1.1.11 versions.
