Typo3 Indexed Search Cross-Site Scripting Vulnerability

TYPO3 is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied input data.

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

Versions 4.0 and 4.0.1 are vulnerable.
