Description Huzaifa S. Sidhpurwala 2012-08-27 03:33:27 UTC

Security researcher Mariusz Mlynski reported that it is possible to shadow the location object using Object.defineProperty. This could be used to confuse the current location to plugins, allowing for possible cross-site scripting (XSS) attacks.
