Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under AI ChatBot for WooCommerce – WoowBot.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 5.0.1, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch AI ChatBot for WooCommerce – WoowBot to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Wordfence PRISM.

The AI ChatBot for WooCommerce – WoowBot plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.0.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to repeatedly trigger RAG document sync operations that issue paid embedding API calls to OpenAI, Gemini, OpenRouter, or xAI charged to the site administrator's stored API key, draining their AI API credits and causing financial loss. The wp_chatbot nonce required to reach this endpoint is emitted to every authenticated frontend visitor via wp_localize_script, making it trivially obtainable by any subscriber-level account.
