Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-43461 is a spoofing vulnerability in the Windows MSHTML Platform that carries a CVSS 3.1 score of 8.8. The flaw is tracked under CWE-451 and affects the MSHTML rendering engine used by multiple Windows components for processing web content.
An unauthenticated remote attacker can exploit the issue by serving specially crafted content that a user must interact with, such as through a web browser or application embedding MSHTML. Successful exploitation allows the attacker to spoof user interface elements, potentially leading to high impacts on confidentiality, integrity, and availability.
Microsoft’s advisory at msrc.microsoft.com details available patches, while CISA lists the CVE in its Known Exploited Vulnerabilities catalog, confirming active exploitation in the wild and requiring prioritized remediation.
EPSS for the vulnerability rose from a low baseline after disclosure to a peak of 0.1624 on 2024-09-18 before receding to the current value of 0.0990, indicating a measurable increase in observed exploitation interest following public release.
