CWE-639 — Authorization Bypass Through User-Controlled Key

This CVE was published Jul 16, 2026 and is one of 26 known issues for this plugin.

Update, patch or deactivate.

Update AI Engine to 3.5.5 or later, or disable and remove it until a fixed version is available.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The AI Engine WordPress plugin before 3.5.5 does not verify that a user owns the chatbot conversation referenced by a client-supplied identifier, allowing users with subscriber-level access to read other users' private conversations and take over their conversation records when the discussions feature is enabled.
