Description Adam Mariš 2016-01-12 15:38:11 UTC 
It was reported that when developers generate html options tags manually, user input concatenated with manually built tags may not be escaped and an attacker can inject arbitrary HTML in to the document. Only manually generated select tag options are impacted.

Vulnerable code:

<%= select('post', 'author_id', "<option value='#{user.id}'>#{user.name}</option>") %>
