🚨 A crafty XSS vulnerability lurks in Liferay Portal's Frontend JS module, allowing attackers to inject malicious scripts through specially crafted URLs! 🔥 Think of it like a restaurant where someone can slip a forged order into the kitchen's ticket system.

If left unaddressed, this could put your entire user base at risk!
