The short answer is: the word Remote in the CVE title describes the attacker’s position and the delivery path, while the CVSS Attack Vector AV:L describes where the exploit actually executes — on the victim’s local machine — and the two are complementary, not contradictory. Background / Overview...

Microsoft’s advisory wording that CVE-2025-59225 is a “Remote Code Execution” vulnerability is not a contradiction with its CVSS Attack Vector of AV:L (Local) — the two statements describe different aspects of the threat: one describes the attacker’s position and delivery capability, the other...

Microsoft’s advisory for CVE-2025-59224 calls the bug a “Remote Code Execution” in Microsoft Excel while the published CVSS vector lists Attack Vector: Local (AV:L) — a phrasing that confuses many defenders. The apparent contradiction is semantic, not technical: the advisory’s “Remote” describes...
