  "title": "Microsoft Edge Security Feature Bypass Vulnerability",
  "description": "\u003Cp\u003EA security feature bypass vulnerability exists when Microsoft Edge improperly handles redirect requests. The vulnerability allows Microsoft Edge to bypass Cross-Origin Resource Sharing (CORS) redirect restrictions, and to follow redirect requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted to a destination website of the attacker\u0027s choice.\u003C/p\u003E\n\u003Cp\u003EIn a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. The attacker could also take advantage of compromised websites, and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.\u003C/p\u003E\n\u003Cp\u003EThe security update addresses the vulnerability by modifying how affected Microsoft Edge handles redirect requests.\u003C/p\u003E",
