CVE-2018-0777 is a critical scripting engine memory corruption vulnerability in Microsoft Edge, affecting Windows 10 and Windows Server 2016. This flaw allows an unauthenticated attacker to execute arbitrary code in the context of the current user, primarily due to how the scripting engine handles objects in memory. With a CVSS score of 7.5 (High) and an EPSS percentile of 98.8%, it presents a significant risk, requiring user interaction (UI:R) but having high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). While not listed in CISA KEV, an Out-of-Bounds Write exploit (EDB-43718) exists, and it has received notable community discussion and media coverage, indicating its potential for exploitation.
