abp-next-admin 10.2.0 through 10.6.0 contains an insecure direct object reference vulnerability in the LINGYUN.Abp.AIManagement module that allows authenticated users to access other users' AI chat conversations by supplying their ConversationId. Attackers holding the Chat permission can call ChatAppService.GetListAsync or SendMessageAsync with a victim's ConversationId GUID to read chat messages and inject messages into that conversation.
