# ChatWiki: authenticated users can overwrite other tenants' fast commands

Link for people: https://infrastack.ai/live/CVE-2026-123624 (this .md is for agents)

ChatWiki before 2.10.0 lets any logged-in user change another tenant's fast commands by guessing sequential record ids sent to the save endpoint. An attacker can rewrite a command's content and point webpage-jump commands at attacker-controlled URLs, then reassign the record to their own tenant.

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

## How to check

- Check the ChatWiki version in use; deployments below `2.10.0` are affected.
- Review whether the fast command save endpoint (`POST /manage/saveFastCommand`) is reachable by tenant users who should not manage other tenants' data.

## Fix

- ChatWiki: upgrade to `2.10.0` or later.

## From the sources

ChatWiki before 2.10.0 contains an insecure direct object reference vulnerability that allows authenticated users to modify other tenants' fast commands by supplying arbitrary sequential ids to POST /manage/saveFastCommand. Attackers can overwrite another tenant's command title, type, content and robot binding, redirecting webpage-jump commands to attacker URLs and reassigning the record to their own tenant.
