On installations which have the Twitter widget activated (disabled by default, but in use on many installations), any authenticated user may add the Twitter widget to their activity / dashboard page. Editing its configuration allows the user to set the twitter_username parameter. The value stored in this parameter will be echoed without sanitation  when the users' activity / dashboard page is requested (by the same or any other user, authenticated or not). According to changes committed  to their Git repository Elgg developers will provide a fix for this issue in the upcoming (?) 1.8.13 release. Reported by: Moritz Naumann http://moritz-naumann.com A CVE ID has, to my knowledge, not yet been assigned. Secunia has assigned it SA52007. A slightly more complete advisory should hit FD and Bugtraq any minute.
