## Overview

The AI Engine  WordPress plugin before 3.6.4 does not verify ownership of a guest's uploaded chatbot files before deletion, authorising the action solely by a client-supplied session cookie value, so an unauthenticated attacker who obtains a victim's session identifier and file reference can delete that victim's uploaded files.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
