AI Analysis
Technical Summary
CVE-2026-89141 is an Insecure Direct Object Reference vulnerability in the AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin affecting all versions up to 3.7.7. It arises from missing validation on the user-controlled 'mediaId' parameter, enabling authenticated users with subscriber-level privileges or higher to retrieve transcribed contents of private audio attachments of other users, including administrators. Exploitation requires the Public API module to be enabled, as the vulnerable REST route is absent when disabled.
Potential Impact
An attacker with subscriber-level or higher access can bypass authorization controls to access sensitive private audio transcription data of other users, including administrators. This leads to a confidentiality breach of potentially sensitive information. There is no impact on integrity or availability reported.
Mitigation Recommendations
No official patch or fix is currently confirmed. Users should disable the Public API module in the plugin settings to prevent access to the vulnerable REST endpoint, as this disables the attack vector. Monitor the vendor advisory for updates regarding an official fix or patch.
