About this tag
The tag cvss av l covers the CVSS attack vector metric value Local (AV:L) and its relationship to Microsoft's Remote Code Execution (RCE) labeling in Office vulnerabilities. Threads explain that Microsoft calls a vulnerability RCE when the attacker can be remote, while CVSS assigns AV:L because the vulnerable code runs on the victim's local machine after processing content like a document. This distinction is not a contradiction but a difference between attacker geography and exploit mechanics. Discussions focus on CVE-2026 vulnerabilities in Word, Excel, and Outlook, emphasizing that AV:L does not mean low risk and that these flaws require user interaction but still pose serious enterprise threats. The tag helps administrators understand patch urgency and risk assessment when CVSS and Microsoft labels appear to conflict.

    CVE-2026-65664 Office RCE Requires Local Access

    Microsoft’s August 11 advisory for CVE-2026-65664, titled “Microsoft Office Graphics Component Remote Code Execution Vulnerability,” carries a CVSS attack vector of AV:L — Local. Those labels can coexist, but Microsoft’s own FAQ explains the relationship poorly enough that administrators could...

    CVE-2026-63513: Office RCE Is Not Network-Reachable

    Microsoft’s August 11 advisory for CVE-2026-63513, titled “Microsoft Office Graphics Component Remote Code Execution Vulnerability,” is not describing a network-reachable Office service that an attacker can hit from the internet. Its CVSS attack vector of AV:L means the vulnerable Office...

    CVE-2026-45643 Word RCE: How “Remote” vs “AV:L” Affects Real Enterprise Risk

    Microsoft describes CVE-2026-45643 as a Microsoft Word Remote Code Execution vulnerability even though its CVSS attack vector is local because “remote” identifies the attacker’s position, while “local” identifies where the malicious code must run to trigger exploitation. The apparent...

    CVE-2026-45456: “Remote Code Execution” with CVSS AV:L in Outlook and Word

    Microsoft labels CVE-2026-45456 as remote code execution because the attacker can be remote from the victim, while the CVSS attack vector is Local because exploitation ultimately occurs through code or content processed on the victim’s own machine, including Outlook’s use of Word rendering. That...

    CVE-2026-44824: Why Microsoft Office RCE Shows AV:L and What Defenders Must Do

    Microsoft labels CVE-2026-44824 as a Microsoft Office remote code execution vulnerability because the attacker can be remote, even though the vulnerable Office code is ultimately triggered on the victim’s local machine after a file or content path is opened, previewed, or otherwise processed...

    CVE-2026-45486 Word RCE vs CVSS AV:L: Remote Attacker, Local Execution Risk

    Microsoft classifies CVE-2026-45486 as a Microsoft Word Remote Code Execution vulnerability even though its CVSS attack vector is Local because the exploit code runs on the victim’s machine after a malicious document or content path reaches the user, while the attacker may be remote from that...

    CVE-2026-45471 Word RCE: Why “Remote” Means Attacker, While CVSS Says Local

    Microsoft classifies CVE-2026-45471 as a Microsoft Word remote code execution vulnerability even though its CVSS attack vector is local, because “remote” describes where the attacker may be sitting, while AV:L describes where the vulnerable code must actually be triggered: on the victim’s...

    CVE-2026-45475 Office RCE Explained: Why “Remote” Matches CVSS AV:L

    CVE-2026-45475 is titled a Microsoft Office Remote Code Execution vulnerability because the attacker can be remote from the victim, while the CVSS attack vector is Local because the vulnerable code is executed on the victim’s own machine through Office processing local content. The apparent...

    CVE-2026-45469 Excel RCE: Why AV:L Still Means Real Patch Urgency

    Microsoft’s CVE-2026-45469 describes a Microsoft Excel remote code execution vulnerability in which the CVSS attack vector is local because exploitation requires code to run on the target machine, typically after a user opens or executes attacker-supplied content. The apparent contradiction is...

    Why Office RCE and CVSS AV:L Can Both Be True (CVE-2026-33095 Explained)

    Microsoft’s title and the CVSS vector are describing two different things, so they are not actually in conflict. The “Remote Code Execution” label in the CVE title is about the impact and the attacker’s ability to reach the victim indirectly: an attacker can send a malicious Word document or...

    Remote Code Execution vs AV:L: Why “remote” still means local file-triggered RCE

    Yes — the apparent mismatch comes from Microsoft using two different layers of description. The CVSS field AV:L is describing the attack vector in scoring terms: the exploit has to be triggered through a local file-processing path on the victim machine, usually by opening or otherwise handling a...
