About this tag
The CVSS tag on WindowsForum.com covers discussions about the Common Vulnerability Scoring System, particularly how CVSS vectors relate to Microsoft Office vulnerabilities. Recurring themes include the distinction between a CVE title's 'Remote Code Execution' label and a CVSS Attack Vector of 'Local' (AV:L), explaining that remote delivery does not mean remote execution. Specific CVSS concepts like 'Changed Scope' (S:C) are also explored, showing how a vulnerability can cross security boundaries. Threads analyze real CVEs from Microsoft's July 2026 security releases, such as CVE-2026-56156, CVE-2026-55033, and CVE-2026-50301, all with CVSS 3.1 base scores of 7.8. The tag helps users understand CVSS scoring nuances for proper vulnerability triage.

    CVE-2026-56156: Excel RCE Is Local CVSS 7.8, Not Network

    CVE-2026-56156 is a Microsoft Excel remote code execution vulnerability that requires malicious content to be processed on the victim’s device, which is why its CVSS vector uses the Local attack vector rather than Network. The apparent contradiction comes from two different meanings of “remote”...

    What CVSS S:C Means for CVE-2026-27928: Changed Scope and Tenant Cross-Access

    In CVSS terms, S:C means the vulnerability has a changed scope: a successful exploit can cross a security boundary and affect something outside the vulnerable component’s own authorization context. In plain English, the attacker is not just influencing the Windows Hello component itself; they...

    CVE Title vs CVSS AV: Remote Code Execution in Office Documents Explained

    Microsoft’s decision to label CVE-2025-62561 as a “Microsoft Excel Remote Code Execution Vulnerability” while its published CVSS vector lists Attack Vector as Local (AV:L) is not a contradiction but a reflection of two different communication goals: the CVE title describes what an attacker can...

    RCE vs AV:L: Understanding CVE-2025-59226 Exploitation Path

    Microsoft’s labeling of CVE-2025-59226 as a “Remote Code Execution” issue while its CVSS Attack Vector is listed as AV:L (Local) is not an error — it’s a product of two different conventions answering two different questions: what the bug allows an attacker to accomplish, and how the attacker...

    RCE vs Local: Decoding CVE Titles and CVSS Vectors in Office Vulnerabilities

    Microsoft’s CVE naming can look contradictory at a glance: a Microsoft Office entry labeled “Remote Code Execution” while its CVSS vector reads AV:L (Local). That apparent mismatch is not a mistake — it’s a product of two separate, sensible conventions colliding: one is a vendor‑level...
