Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability
Published October 16, 2026Updated October 16, 2026
Source data
Overview
Access of resource using incompatible type ('type confusion') in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.
Impact & technical details
A separate impact classification is not supplied in this record. See the source advisory.
According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.
How could an attacker exploit this vulnerability? An unauthenticated attacker could host a specially crafted webpage and convince a user to visit it using an affected version of Microsoft Edge. Successful exploitation could allow the attacker to execute code within the browser renderer process. User interaction is required.
