Remote code execution in Microsoft Edge (Chromium-based) stems from a type confusion flaw (CWE-843) that an unauthorized attacker can trigger over the network to run arbitrary code, provided the victim interacts with attacker-controlled web content. Microsoft self-reported and has shipped a fix; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. The high attack complexity (AC:H) and required user interaction (UI:R) temper an otherwise network-reachable, unauthenticated attack surface.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
