Rails 3.0.11 has been released. This is a patch-level release containing bug fixes and an important security fix.

Possible XSS vulnerability in the translate helper method in Ruby on Rails

There is a vulnerability in the translate helper method which may allow an attacker to insert arbitrary code into a page.

• Versions Affected: 3.0.0 and later, 2.3.X in combination with the rails_xss plugin
• Not Affected: Pre-3.0.0 releases, without the rails_xss plugin, did no automatic XSS escaping, so are not considered vulnerable
• Fixed Versions: 3.0.11, 3.1.2

Please see the rubyonrails-security posting and the changelog item below, for more details.

Changes

Action Mailer:

• No changes

Action Pack:

• Fix XSS security vulnerability in the translate helper method. When using interpolation in combination with HTML-safe translations, the interpolated input would not get HTML escaped. GH 3664

  Before:

  translate('foo_html', :something => '<script>') # => "...<script>..."
  

  After:

   translate('foo_html', :something => '<script>') # => "...<script>..."

• Implement a workaround for a bug in ruby-1.9.3p0 where an error would be raised while attempting to convert a template from one encoding to another.

  Please see http://redmine.ruby-lang.org/issues/5564 for details of the bug.

  The workaround is to load all conversions into memory ahead of time, and will only happen if the ruby version is exactly 1.9.3p0. The hope is obviously that the underlying problem will be resolved in the next patchlevel release of 1.9.3.

• Fix assert_select_email to work on multipart and non-multipart emails as the method stopped working correctly in Rails 3.x due to changes in the new mail gem.

• Fix url_for when passed a hash to prevent additional options (eg. :host, :protocol) from being added to the hash after calling it.
