Unspecified vulnerability in Oracle Java SE 7u40 and earlier and JavaFX 2.2.40 and earlier allows remote attackers to affect confidentiality via unknown vectors.

A flaw was found in the way javadoc (Java API Documentation Generator) created a JavaScript code used to set browser window title when navigating between pages of the generated API documentation. An input from user was not properly escaped before being used as part of the JavaScript string. A specially crafted input could "break out" of the JS string and execute arbitrary JavaScript in the context of the domain that hosts generated API documentation, allowing a Cross-Site Scripting attacks.
