Subject: Code Injection Vulnerability in pLog

I believe I have discovered a vulnerability in the open source blog
software known as pLog. Register.php doesn't seem to check for script
tags in the username or blog name fields in the account sign up form.

This allows injection of potentially malicious code into the page. Since
the names of blogs are displayed on the summary.php page, anyone who
sees that page would be subject to execution of said code.

I have contact the developers about this. They have verified the bug and
are working on a fix.
