A vulnerability has been reported in ExpressionEngine, which can be exploited by malicious users to conduct script insertion attacks.
Input passed via the "avatar" parameter in system/index.php (when "M" is set to "select_avatar" and "C" is set to "myaccount") is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in the context of an affected site when the malicious avatar is displayed.
The vulnerability is reported in versions 1.6.4 to 1.6.6.
Solution: The vulnerability is reportedly fixed in version 1.6.7.
