<p>A security feature bypass vulnerability exists in the way that Microsoft Edge handles whitelisting. Edge depends on a default whitelist of sites where Adobe Flash will load without user interaction. Because the whitelist was not scheme-aware, an attacker could use a man in the middle attack to cause Flash policies to be bypassed and arbitrary Flash content to be loaded without user interaction.</p> <p>The security update addresses the vulnerability by modifying how Microsoft Edge handles whitelisting.</p>
