JW Player - logo.link Cross-Site Scripting

source: https://www.securityfocus.com/bid/55199/info

JW Player is prone to a cross-site scripting vulnerability because it fails to properly 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 can allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

JW Player 5.10.2295 and prior versions are also vulnerable.
