Hello all, There is a bug in "Log" function of Search Unleashed by John Godley, version 0.2.10. This plug-in stores search queries but does not validates stored data and put them back "raw" to browser. HTML and Java Script can be injected with search request: /blog/?s=%3Ctextarea+onmouseover%3D%22alert%28document.cookie%29%3B%22%3 E%3C%2Ftextarea%3E&searchbutton=go%21 To execute injected code admin have to go to Manage -> Search Unleashed -> Log (and in my example point his cursor to text area). Author was notified by his bug tracker: http://urbangiraffe.com/tracker/issues/show/60 Regards, -- Krzysztof Burghardt <krzysztof (at) burghardt (dot) pl [email concealed]> http://www.burghardt.pl/
