Microsoft Internet Explorer Scripting Engine Memory Corruption Vulnerability — Microsoft Internet Explorer contains a memory corruption vulnerability due to the way the Scripting Engine handles objects in memory. Successful exploitation could allow remote code execution in the context of the current user. Listed in the CISA KEV catalog (added 2021-11-03) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~87%. Treat it as real and prioritize remediation over triage.
