## Technical details

A missing authorization vulnerability (CWE-862) exists in the OpenAI thread and message API endpoints of GROWI. The root cause is a failure to verify if the requesting user has permission to access or modify a specific thread or message. An authenticated attacker with network access can exploit this by supplying the identifier of a shared AI assistant to interact with data belonging to other users. This allows for unauthorized viewing (Confidentiality) and tampering (Integrity) of AI-related communications. The issue is resolved in GROWI v7.4.6.
