Cross Site Scripting: link to HREF

Even though Rails will escape the link provided to link_to, values starting with “javascript:” or “data:” are unescaped and dangerous.

Railroader will warn on if user values are used to provide the HREF value in link_to or if they are interpolated at the beginning of a string.

The --url-safe-methods option can be used to specify methods which make URLs safe.

See here for more details.
