About this tag
The cvss scoring tag on WindowsForum.com covers discussions about the Common Vulnerability Scoring System, particularly how CVSS Attack Vector (AV) values relate to Microsoft's vulnerability advisories. Threads explain apparent contradictions where Microsoft labels a flaw as Remote Code Execution while CVSS shows AV:L (Local), clarifying that the CVE title describes the impact while CVSS AV describes where the exploit trigger occurs. Examples include Excel and Office parsing vulnerabilities where malicious files are delivered remotely but executed locally. The tag focuses on interpreting CVSS vectors correctly, distinguishing between attacker origin and technical trigger conditions, and understanding Microsoft's advisory naming conventions.

    CVE-2026-55131: Patch Excel RCE With July 14 Office Updates

    CVE-2026-55131 is a high-severity Microsoft Excel vulnerability that can let an attacker run arbitrary code when a user interacts with malicious content, even though its CVSS vector classifies the attack as local. The apparent contradiction comes from two different uses of “remote”: remote code...

    Excel “Remote Code Execution” vs CVSS AV:L: Why They Aren’t Contradictory

    Microsoft’s naming here is not contradictory once you separate the attack vector from the effect. In CVSS, AV:L means the exploit requires local interaction on the target machine, or a local foothold in the attack path, while Remote Code Execution in Microsoft’s title describes the impact: the...

    CVE-2026-26110 Explained: Remote Delivery, Local Execution in Office

    Microsoft’s advisory for CVE-2026-26110 labels the defect as a “Remote Code Execution” (RCE) vulnerability in Microsoft Office, yet the published CVSS Attack Vector is listed as Local (AV:L) — this apparent contradiction is deliberate and explains two different questions about risk: who can...

    Understanding Excel CVE-2026-20957: Remote RCE vs Local Trigger in CVSS

    Microsoft’s CVE-2026-20957 advisory names the flaw as a “Microsoft Excel Remote Code Execution Vulnerability,” yet the published CVSS vector lists the Attack Vector as Local (AV:L) — a pairing that looks contradictory until you separate attacker origin and operational impact from the technical...

    Remote Delivery, Local Execution: Decoding Excel Parsing RCE and CVSS AV

    Microsoft’s brief CVE title and the CVSS vector are answering two different questions: the CVE headline tells you what an off‑host attacker can ultimately accomplish (arbitrary code execution on a target), while the CVSS Attack Vector (AV) reports where the vulnerable code must be executed at...
