Topic Calendar is a quite widespread MOD for phpBB all versions that adds
a calendar to the board, using topics as event. 

Due to improper filtering done by the script 'calendar_scheduler.php' a
remote attacker can cause the Topic Calendar product to include arbitrary
HTML and/or JavaScript.

An attacker may use this bug to preform phishing attacks.

Solution : Disable this mod or upgrade to a newer version
