# Bonbon WordPress theme: unauthenticated PHP object injection, up to 1.11

Bonbon versions up to 1.11 deserialize attacker-supplied PHP objects without authentication. Successful exploitation can let an attacker run code or change data on the affected site.

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

## Affected

- wordpress-theme:Bonbon affected <= 1.11 fixed ?

## How to check

Appearance > Themes, or the Version line in wp-content/themes/bonbon/style.css; 1.11 or lower is affected. With WP-CLI: wp theme list | grep bonbon

## Fix

No fixed version published as of 2026-10-29. Remove or deactivate the Bonbon theme, or switch theme, until the vendor releases a fix; a WAF or Patchstack virtual patch can reduce risk.
