Description Huzaifa S. Sidhpurwala 2016-08-01 06:34:32 UTC 
Security researcher Nikita Arykov reported that JavaScript event handler attributes on a <marquee> tag will execute inside a sandboxed iframe that does not have the allow-scripts flag set. This could result in a cross-site scripting (XSS) vulnerability in a site that depends on the iframe sandbox for sanitization and does no other content filtering.
