CVE-2012-1099: XSS via posted select tag options

March 13, 2012 (updated August 8, 2019)

Ruby on Rails is vulnerable to remote cross-site scripting because the application does not validate manually generated select tag options upon submission to actionpack/lib/action_view/helpers/form_options_helper.rb. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user’s browser within the trust relationship between their browser and the server.
