Rails update fixes security issue
Rails update fixes security issue
Wednesday, 06 April 2011

Rails 3.0.6, released today, contains an important security fix. If you can't upgrade there is also a security patch to fix the issue.

Rails versions 3.0.x prior to 3.0.6 contain an XSS vulnerability which manifests itself via the auto_link method such that this method automatically marks input strings as "html safe" even if the input is from an unknown origin. Users are therefore being urged to update to Rails 3.0.6 which can be downloaded from github. This upgrade will ensure that content passed to auto_link will be automatically escaped for you.

In the event that upgrading Rails 3 isn't something you want to do there is also a security patch that has the same effect.

If you don't want either to upgrade Rails or apply the patch then the advice from the Rails blog is to change calls to auto_link as follows: 

<%= sanitize(auto_link(params[:content])) %>

If you trust the input, then this is the change to make:

<%= raw(auto_link(params[:content])) %>
