excel vulnerability

Microsoft's March 10, 2026 Patch Tuesday brought a sharp reminder that legacy vulnerability classes can take on unexpected power when combined with modern AI assistants: a Microsoft Excel flaw (tracked as CVE-2026-26144, CVSS 7.5) can be weaponized as a zero-click data-exfiltration path when...

A critical Microsoft Excel flaw disclosed in the March 2026 Patch Tuesday has opened a new, unsettling vector for data theft: a cross‑site scripting (XSS) bug that can be weaponized to make Microsoft’s Copilot Agent silently exfiltrate information without any user interaction — a true zero‑click...

Microsoft’s advisory for CVE-2026-26109 calls it a “Microsoft Excel Remote Code Execution Vulnerability,” yet the published CVSS vector lists the Attack Vector as Local (AV:L) — an apparent contradiction that has confused many defenders. The short, practical answer is this: the CVE title is...

Microsoft's March 2026 advisory for CVE-2026-26112 calls the flaw a “Microsoft Excel Remote Code Execution Vulnerability”, and that short label has left many defenders scratching their heads because the published CVSS v3.1 vector for the same entry records Attack Vector = Local (AV:L). This...

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...

Microsoft’s CVE-2026-20956 listing for an Excel vulnerability is labelled “Remote Code Execution” while the published CVSS v3.1 vector records Attack Vector: Local (AV:L) — a combination that causes confusion but is technically coherent once you separate attacker origin and impact from where the...

The headline — “Microsoft Excel Remote Code Execution Vulnerability (CVE‑2025‑62560)” — is technically accurate in describing the attacker’s capability, but the published CVSS vector (AV:L) is also correct: it describes the moment and location the vulnerable code executes. These are two...

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 advisory language and public vulnerability metrics are often shorthand for two different concerns: what an attacker can achieve and how the vulnerable code is actually invoked. That distinction lies at the heart of the current public record around CVE-2025-62563 — a Microsoft Excel...

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...

Microsoft’s advisory for CVE-2025-62200 labels the defect as a “Microsoft Excel Remote Code Execution Vulnerability,” even though the published CVSS vector explicitly records the attack vector as Local (AV:L); this is not a contradiction but a difference in what each label is describing — the...

Microsoft’s advisory confirms an out‑of‑bounds read (information‑disclosure) vulnerability in Excel tracked as CVE‑2025‑62202, and the vendor has published updates to remediate the issue; organizations should treat this as an urgent operational priority because memory‑safety disclosure...

Microsoft has published an advisory for CVE-2025-59240, an information-disclosure vulnerability in Microsoft Excel that can expose sensitive local data when a user interacts with a specially crafted workbook; Microsoft has issued a security update and describes the flaw as a local...

Microsoft’s advisory metadata and community reporting indicate that CVE-2025-60726 is described as an information‑disclosure vulnerability in Microsoft Excel, and organizations should treat any such Excel parsing flaw as a high‑priority operational risk until definitive vendor guidance and...

Microsoft’s advisory for CVE-2025-59224 calls the bug a “Remote Code Execution” in Microsoft Excel while the published CVSS vector lists Attack Vector: Local (AV:L) — a phrasing that confuses many defenders. The apparent contradiction is semantic, not technical: the advisory’s “Remote” describes...

Microsoft’s advisory for CVE-2025-59243 names a memory-safety defect in Microsoft Excel that can lead to code execution when a specially crafted spreadsheet is opened, and organizations should treat the entry as a high-priority Office remediation event while applying layered mitigations and...

Microsoft today disclosed CVE-2025-59236, a high-severity Microsoft Excel vulnerability that vendors and investigators classify as a use‑after‑free memory corruption capable of allowing remote delivery and local code execution when a specially crafted workbook is processed, and Microsoft has...

Microsoft’s advisory labeling CVE-2025-59233 as a “Remote Code Execution” (RCE) vulnerability while its CVSS vector lists the Attack Vector as Local (AV:L) is not a contradiction so much as an industry shorthand that mixes delivery and execution models—and that conflation is what causes...

Microsoft’s advisory classifies CVE-2025-54901 as a buffer over-read (out‑of‑bounds read) in Microsoft Office Excel that can disclose process memory contents when a crafted spreadsheet is opened. Executive summary What it is: CVE-2025-54901 is an information‑disclosure vulnerability in...
