Aureus ERP before 1.5.0 fails to scope message lookups to the current record in ChatterPanel, allowing authenticated users to access arbitrary messages. Attackers can submit sequential message IDs to read, edit, delete, or pin messages from other departments or companies, and enumerate all notes in the system.

Aureus ERP before 1.6.0 contains a stored cross-site scripting vulnerability in the Chatter field-change log where oldvalue and newvalue entries are rendered without proper escaping. Any user permitted to edit tracked text fields can inject malicious markup that executes when other users, including administrators, view the record's Chatter panel.

Aureus ERP through 1.6.0 stores the Payment Term note field unsanitized and renders it as raw HTML in the Accounting plugin. Authenticated users with payment-term create permission can submit arbitrary JavaScript to the payment-terms endpoint, which persists to the database and executes in browsers of all users viewing that Payment Term record.
