EspoCRM is an open source customer relationship management application. Prior to 9.3.7, a portal user with stream access to a parent record can directly fetch a Note through the portal Note API and read an internal stream note when the note identifier is known. Stream list responses correctly hide notes whose isInternal field is true, but the direct single-Note access check does not enforce that restriction, exposing internal agent content. This issue is fixed in version 9.3.7.
