AI Engine < 3.6.4 - Unauthenticated Cross-Session Chatbot File Deletion via Forgeable Session Cookie
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
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.
