cve-2026-45463

CVE-2026-45463 is a Microsoft Office remote code execution vulnerability that can be confusing because Microsoft labels it as remote while CVSS assigns a Local attack vector. This apparent contradiction arises from different definitions: Microsoft considers the attacker's ability to be remote from the victim, whereas CVSS focuses on where the vulnerable component is attacked from. Exploitation requires malicious code or content to be processed on the victim's own machine. Discussions on WindowsForum clarify this terminology gap and help users understand the real risk. The tag covers analysis of the CVE, its CVSS scoring, and Microsoft's security vocabulary.
