# Filmax WordPress theme: unauthenticated PHP object injection, cvss 9.8

Filmax versions up to 1.1.11 unserialize untrusted input, so an unauthenticated visitor can inject a PHP object. The sources say this is critical with a CVSS score of 9.8, which suggests code execution or full site takeover, but they give no further detail.

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

## How to check

- Check the installed Filmax version in the theme's style.css or the WordPress Appearance > Themes screen
- Confirm whether the site runs Filmax at all: unknown beyond the version check

## Fix

- Move Filmax above `1.1.11`; the fixed version is not stated in the sources

## Timeline

- 2026-10-29T16:26:00+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-62009

## From the sources

Unauthenticated PHP Object Injection in Filmax <= 1.1.11 versions.
