TYPO3 Modern Guestbook / Commenting System Extension Unspecified Cross Site Scripting Vulnerability

TYPO3 Modern Guestbook / Commenting System extension is prone to a cross-site scripting vulnerability because the application fails to sufficiently sanitize user-supplied input.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.

Versions prior to Modern Guestbook / Commenting System 2.7.2 are vulnerable.
