AI-suggested
Until a fix is available, restrict access to the AI CMS chat module to trusted users and monitor for suspicious activity related to conversation ID enumeration or unauthorized chat access.
Description
JeeSite versions 5.11.0 through 5.19.1 have an insecure direct object reference vulnerability in the AI CMS chat module. Authenticated users can access, delete, or append to other users' AI chat conversations by exploiting missing and reversed ownership checks when calling certain chat-related endpoints. The vulnerability requires knowledge or derivation of a victim's conversation ID. The CVSS score is low, reflecting the need for authentication and high attack complexity.
