CVE-2018-8391 is a remote code execution vulnerability in the ChakraCore scripting engine, affecting Microsoft ChakraCore. This flaw stems from how the engine handles objects in memory, leading to memory corruption. With a CVSS score of 7.5 (High), successful exploitation could allow an unauthenticated attacker to execute arbitrary code with high impact on confidentiality, integrity, and availability, though it requires user interaction and high attack complexity. There is no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed in CISA's KEV catalog, indicating no active exploitation. Community discussion and media coverage are minimal, with only one article mentioning its fix in a past Patch Tuesday.
