About this tag
The cvss tag on WindowsForum.com covers discussions about Common Vulnerability Scoring System vectors as applied to Microsoft security advisories, particularly Office and Windows vulnerabilities. Threads explain how CVSS attack vectors like Local (AV:L) and scope changes (S:C) clarify whether a remote code execution flaw is network-reachable or requires local processing. Recurring themes include interpreting Microsoft's RCE titles, CVSS 3.1 base scores such as 7.8, and practical guidance for patching via monthly security updates. The content focuses on helping IT professionals and administrators understand CVSS metrics to prioritize fixes for vulnerabilities like heap-based buffer overflows in Office components.

    CVE-2026-65657: Office RCE Is Local, Not Network-Reachable

    Microsoft’s August 11 advisory for CVE-2026-65657, titled “Microsoft Office Remote Code Execution Vulnerability,” is correctly scored with a CVSS attack vector of Local (AV:L). The apparent contradiction comes from treating “remote code execution” as a statement about where the attacker sits. It...

    CVE-2026-63519: Patch Office Graphics RCE Despite AV:L

    Microsoft’s August 11, 2026 advisory for CVE-2026-63519, titled “Microsoft Office Graphics Component Remote Code Execution Vulnerability,” is not describing an internet-facing Office service that an attacker can compromise directly. The advisory’s CVSS attack vector is Local, or AV:L, and...

    CVE-2026-63518: Word RCE Is Local, Not Network-Reachable

    Microsoft’s classification of CVE-2026-63518 as a “Microsoft Office Word Remote Code Execution Vulnerability” does not mean an unauthenticated attacker can reach a Word installation directly over the network and run code from afar. The advisory, published by the Microsoft Security Response...

    CVE-2026-63515 Office RCE Is Local, Not Network-Exposed

    Microsoft’s August 11 advisory for CVE-2026-63515, titled “Microsoft Office Remote Code Execution Vulnerability,” is not describing an Office service that an unauthenticated attacker can reach directly over the network. Its CVSS attack vector is Local, and Microsoft’s own FAQ says exploitation...

    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”...

    CVE-2026-55033: Fix Word RCE With July 14, 2026 Updates

    CVE-2026-55033 is a Microsoft Word code-execution vulnerability that can be delivered by a remote attacker but must be triggered through local processing on the victim’s device. That distinction explains the apparently contradictory labels: Microsoft classifies the outcome as remote code...

    CVE-2026-50301 Office RCE: Update Office 2016 to 16.0.5561.1000

    CVE-2026-50301 is a Microsoft Office heap-based buffer overflow that can let an attacker run code on a victim’s PC, but its CVSS vector is Local, not Network. The apparent contradiction comes from two different uses of “remote”: Microsoft’s vulnerability title describes the attacker-controlled...

    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: Excel RCE Explained

    Microsoft’s CVE title and the CVSS Attack Vector are answering two different — but complementary — questions: the CVE headline “Remote Code Execution” signals attacker origin and impact, while the CVSS Attack Vector value AV:L (Local) documents where the vulnerable code is executed at the moment...

    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...

    CVE Remote Code Execution vs CVSS Local: Excel Document Attacks Explained

    Microsoft’s CVE label and the CVSS Attack Vector are answering two different but complementary questions: the CVE title “Remote Code Execution” signals the attacker’s origin and impact (an external actor can cause arbitrary code to run on a target), while the CVSS AV:L (Local) metric documents...

    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...
