-------- DESCRIPTION  
---------------------------------------------------------

The Flag Content module enables users to flag nodes and users for the
attention of a site maintainer (e.g. for abuse, spam, trolling, ...etc.). In
some specific cases, the module does not sanitize before outputting the
Reason field, resulting in a cross-site scripting (XSS [1]) vulnerability.
Such an attack may lead to a malicious user gaining full administrative
access.
