About this tag
The tag 'excel rce' covers discussions about Remote Code Execution vulnerabilities in Microsoft Excel, focusing on the apparent contradiction between CVE titles that say 'Remote Code Execution' and CVSS Attack Vector values that are marked as Local (AV:L). Posts explain that this split is intentional: the CVE title describes the attacker's origin and impact, while the CVSS vector documents where the vulnerable code executes at the moment of exploitation. Examples include CVE-2026-20957 and CVE-2025-62556, with diagrams illustrating remote delivery to a local workstation leading to RCE and server-side parsing. The content clarifies that the discrepancy is not a mistake but a complementary view of the same flaw.
