A number of XSS flaws were reported in Cumin. These flaws could be used by a remote attacker to inject arbitrary web script on a web page displayed by Cumin.
To solve the problem, xmlescape() (as defined in wooly/python/wooly/util.py, a simple wrapper around xml.sax.saxutils.escape()) is called on any values that are displayed on a web page and originate outside of Cumin, or through a form submitted by a user. Many of these have been corrected upstream in r5238 [1].
