local execution

The tag local execution on WindowsForum.com covers discussions about code or processes that run directly on a local machine, often in the context of security vulnerabilities. A prominent example is the analysis of CVE-2026-26109, a Microsoft Excel Remote Code Execution Vulnerability, where the CVSS attack vector is listed as local (AV:L) even though the attacker may be remote. This apparent contradiction is explained by distinguishing between the attacker's location and where the vulnerable code executes—inside a local process on the victim endpoint. The tag explores how local execution is a key factor in understanding exploit mechanics, CVSS scoring, and defense strategies for Windows and Microsoft Office environments.
