Description Huzaifa S. Sidhpurwala 2012-11-17 06:57:45 EST

Security researcher Masato Kinugawa reported that when script is entered into the Developer Toolbar, it runs in a chrome privileged context. This allows for arbitrary code execution or cross-site scripting (XSS) if a user can be convinced to paste malicious code into the Developer Toolbar.
