My Little Homepage Web log, guestbook, and forum are prone to a script injection vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would be able to access properties of the site, potentially allowing for theft of cookie-based authentication credentials. Other attacks are also possible. 

BBCode example have been provided:

[link=javascript:alert(123)]Link[/link]
[link]javascript:alert(123)[/link]
