SafeAnchor

SafeAnchor wraps around Rails's default link_to helper and sanitize method to output always output a sanitized anchor tag.

This follows a secure-by-default principle and can be turned off by passing an optional argument keep_dirty: true when using the link_to helper.

Add this line to your application's Gemfile:

gem 'safe_anchor'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install safe_anchor

SafeAnchor is secure-by-default.

<%= link_to "Dangerous Anchor", "javascript: alert('Boo!')" %>
# <a>Dangerous Anchor</a>

Turning off sanitization.

<%= link_to "Dangerous Anchor", "javascript: alert('Boo!')", keep_dirty: true %>
# <a keep_dirty="true" href="javascript: alert('Boo!')">Dangerous Anchor</a>
