Description

EspoCRM 4.0.0 before 10.0.7 contains an access control vulnerability that allows authenticated users to read audited field values restricted by field-level security by fetching individual stream notes. Users with stream access to a parent record can request GET /Note/{id}, which skips the NoteAccessControl filter, and recover data.attributes.was and became values of restricted fields.
