# abp-next-admin AI chat lets users read others' conversations by ID

The LINGYUN.Abp.AIManagement module in abp-next-admin 10.2.0 through 10.6.0 does not check ownership of a chat conversation when given its ConversationId. An authenticated user with the Chat permission can read another user's AI chat messages and inject messages into that conversation.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the abp-next-admin version in the project's package references: versions 10.2.0 through 10.6.0 are affected.
- Confirm whether the LINGYUN.Abp.AIManagement module is installed and in use.

## Fix

- Upgrade abp-next-admin to a release after `10.6.0`, as listed in the NVD record; the exact fixed version is unknown from the sources.

## From the sources

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.
