Description Vincent Danen 2011-08-17 16:40:19 UTC
An XSS vulnerability in the strip_tags helper in Ruby on Rails was reported
[1] where, using specially crafted output, an attacker can successfully inject HTML into the document, which can be used to inject arbitrary javascript into the rendered page.

This is corrected in upstream 3.0.10, 2.3.13, and 3.1.0rc5 versions.  Patches are available in the advisory [1] and in git [2].
