Summary
The AI Engine WordPress plugin before version 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.
Risk Assessment

Recommendation
Immediately update the AI Engine plugin to version 3.5.5 or later, which includes the necessary security fixes.
Other vulnerabilities in AI Engine
See all- CVE-2026-75798Medium
The AI Engine WordPress plugin before version 3.7.2 does not perform an authorisation check on one of its administration-only features, relying instead on a token it hands out to anonymous visitors. This allows unauthenticated attackers to run AI queries of their own choosing against the site owner's configured provider account.
- CVE-2026-16955Medium
The AI Engine WordPress plugin before version 3.6.6 does not confine a caller-supplied file path before reading it and forwarding the contents to an external service, allowing users with a subscriber-level account to read arbitrary files from the server and exfiltrate them. This requires a non-default public API feature to be enabled; otherwise the issue is reachable by an administrator, which on multisite allows a non-super subsite administrator to read network-shared configuration and secrets.
- CVE-2026-65545High
Unauthenticated Cross Site Scripting (XSS) vulnerability in AI Engine plugin up to version 3.6.8. An unauthenticated attacker can inject malicious scripts.
- CVE-2026-27407High
AI Engine versions up to 3.4.9 have a vulnerability that allows for editor privilege escalation.
