Gamezone WordPress theme: Unauthenticated PHP Object Injection
Summary
The Gamezone WordPress theme by ThemeREX, up to and including version 1.1.11, contains an unauthenticated PHP object injection flaw (CWE-502). An attacker can send crafted data to the website without logging in, which can lead to harmful actions on the server, such as code execution, depending on the gadget classes available in the installation. At the time of writing, no fixed version or vendor advisory has been found, and the NVD status is Deferred.
Affected
- Gamezone WordPress theme, all versions up to and including 1.1.11
Fixed in
Unknown.
- No fixed version confirmed by the vendor at the time of writing.
Workaround
- No vendor workaround published.
- Remove or replace the theme if it is installed or active.
- Restrict access to the site with a WAF with virtual patching, if a rule for this CVE is available.
Exploitation
- Not listed in CISA KEV at the time of writing.
- No reports of exploitation in the wild and no public proof of concept found.
- No EPSS score published yet.
- The vulnerability needs no authentication (PR:N, AV:N), which raises the risk if the theme is reachable.
Our recommendation
- Check immediately whether the Gamezone theme is installed or active on any site, including staging sites and old theme folders.
- If it is in use, replace it with a maintained theme or restrict access behind a WAF with virtual patching.
- Keep WordPress core, PHP and all plugins up to date and remove unused plugins.
- Review web server logs for unusual POST requests.
- Monitor the Patchstack advisory and CISA KEV for updates.
