Skull-Splitter PHP Guestbook HTML Injection Vulnerability

PHP Guestbook is prone to an HTML-injection vulnerability. This issue is due to a lack of proper sanitization of user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would be executed in the context of the affected website, potentially allowing for the theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.
