Microsoft disclosed CVE-2026-40361, a Microsoft Word remote code execution vulnerability, in its Security Update Guide on May 12, 2026, warning that the bug is serious enough to merit patching even though public technical detail remains limited. That combination — a confirmed vendor advisory, a...

CVE-2026-40421 is a Microsoft Word information disclosure vulnerability listed in Microsoft’s Security Update Guide as of May 12, 2026, affecting the Office document-processing stack where a crafted Word file or related content can expose data that should remain unavailable to an attacker. The...

Microsoft’s CVE-2026-33822 entry for Microsoft Word Information Disclosure Vulnerability is a good example of why vendor metadata matters as much as the CVE label itself. The public record may be sparse on exploit mechanics, but Microsoft’s own framing tells defenders that the issue is real...

Microsoft shipped fixes for two recently disclosed critical Microsoft Office vulnerabilities—CVE‑2026‑26110 and CVE‑2026‑26113—that can lead to arbitrary code execution when a crafted file is processed locally, and defenders should treat these updates as high priority because the Outlook and...

Microsoft has released patches for two newly disclosed critical vulnerabilities in Microsoft Office—tracked as CVE-2026-26110 and CVE-2026-26113—and administrators and everyday users should treat the update as urgent: both flaws allow remote code execution in the context of the current user and...

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...

Microsoft’s advisory for CVE-2026-26113, labeled as a “Microsoft Office Remote Code Execution Vulnerability,” has sparked confusion across security teams because the published CVSS vector lists the Attack Vector as Local (AV:L) — a seeming contradiction that deserves a careful, technical...

Microsoft’s security tracking lists CVE-2026-21258 as an Excel information‑disclosure vulnerability, but the public record remains intentionally terse: the vendor entry confirms a vulnerability exists and that updates are the recommended remediation, yet Microsoft’s advisory omits low‑level...

Title: Why CVE-2026-20955 is Called “Remote Code Execution” Even Though CVSS Says AV:L (Local) Executive summary — short answer The phrasing “Remote Code Execution” in the CVE title describes the origin of the attack (an attacker who is remote from the victim can deliver the exploit), not...

Microsoft’s advisory for CVE-2026-20955 labels the bug as a “Microsoft Excel Remote Code Execution Vulnerability,” yet the published CVSS Attack Vector for the issue is Local (AV:L) — a wording mismatch that has left many admins and vulnerability managers asking whether Microsoft misclassified...

Short answer (TL;DR) The CVE title says "Remote Code Execution" because a remote attacker can deliver a malicious Word file and cause code to run on the victim machine (attacker origin / impact). The CVSS Attack Vector = Local (AV:L) because the vulnerable code actually executes inside a local...

Microsoft’s January 2026 security roll‑up includes a newly tracked elevation‑of‑privilege entry — CVE‑2026‑20943 — tied to Microsoft Office Click‑to‑Run (C2R) components, and system administrators should treat the advisory as confirmed and actionable while understanding that public technical...

Microsoft’s Security Update Guide lists a vulnerability identified as CVE-2025-64677 described as an Office “Out‑of‑Box Experience” (OoBE) spoofing issue — a presentation‑layer flaw that can be used to impersonate setup or first‑run UI elements and coerce users into granting access, consenting...

The headline for CVE-2025-62558 — described as a Microsoft Word Remote Code Execution vulnerability — is factually correct about the impact but can be misleading if you treat it as a literal description of the CVSS Attack Vector. Microsoft’s advisory and the CVE title signal that an off‑host...

Microsoft’s security telemetry just added another Office advisory to the pile: CVE-2025-62554, a type‑confusion vulnerability in Microsoft Office that vendors classify as a Remote Code Execution (RCE) risk and that — based on current public records — appears to allow code execution in the...

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...

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...

Microsoft has recorded CVE-2025-60728 as a Microsoft Excel information‑disclosure vulnerability that, according to vendor metadata, stems from an untrusted pointer dereference and can allow disclosure of information when a specially crafted Excel file is processed; the entry was published on...
