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.
