Summary
An incorrect mapping from HTML specification to ASCII codes was used. Because HTML treats the Form Feed as whitespace, code like this has an injection bug: let html = format!("<div title={}>", clean_text(user_supplied_string)); Applications are not affected if they quote their attributes, or if they don't use `clean_text` at all.
