The sanitizer in sanitized-values.ts blocks javascript:/vbscript: in form[action], but its badTags/badAttributes lists leave out button, input and formaction, so a submit button or image input can override the form action with an unsanitized javascript: url. Add BUTTON/INPUT and formaction to the lists so the per-control override is checked the same as form[action].
