Out-of-bounds read in Microsoft Excel and related Office products exposes adjacent process memory to local information disclosure when a user opens a specially crafted spreadsheet file. The flaw spans a broad set of Microsoft Office versions across Windows and macOS - including Excel 2016, Office 2019, LTSC 2021/2024, Microsoft 365 Apps for Enterprise, and Office Online Server - with vendor-released patches now available for all affected builds. No active exploitation has been confirmed by CISA KEV, and EPSS places exploitation probability at 0.35% (27th percentile), consistent with SSVC's assessment of no current exploitation and non-automatable delivery.
Untrusted pointer dereference in Microsoft Excel exposes sensitive in-process memory to a local attacker across virtually the entire Office product family - Excel 2016 through Office LTSC 2024 on Windows and macOS, plus Office Online Server. An attacker must deliver a crafted spreadsheet and induce the victim to open it; successful exploitation yields high confidentiality impact with no integrity or availability effect. No public exploit code or active exploitation has been identified; EPSS at 0.46% (37th percentile) and SSVC exploitation status of 'none' are consistent with low real-world risk at this time.
Information disclosure in Microsoft Office (Microsoft 365 Apps, Office 2016/2019, Office LTSC 2021/2024, and Office for Mac) via an out-of-bounds read (CWE-125) lets an attacker leak sensitive memory contents when a victim opens a maliciously crafted document. The CVSS 3.1 base score is 7.1 (AV:L/AC:L/PR:N/UI:R), reflecting local exploitation that requires user interaction but no prior authentication. Microsoft is the reporting source and has published a fix; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Out-of-bounds read in Microsoft Excel's spreadsheet parser (CWE-125) exposes affected systems to both local information disclosure and application crash when a victim opens a specially crafted file, spanning Excel 2016 through Office LTSC 2024 and Office 365 for Mac. The CVSS vector (AV:L/UI:R/A:H) reveals that while the CVE description emphasizes information disclosure, the primary real-world impact is application availability - the invalid memory read can crash Excel (A:H), with incidental memory content leakage (C:L) as a secondary effect. No public exploit code has been identified at time of analysis and CISA SSVC assigns exploitation status of none, consistent with a low EPSS score of 0.31% at the 23rd percentile.
Heap-based buffer overflow in Microsoft Office Excel triggers a local information disclosure when a target user opens a maliciously crafted document. Affecting Excel 2016 through Office LTSC 2024 and Microsoft 365 Apps for Enterprise on both Windows and macOS, the vulnerability yields only limited confidentiality impact (C:L) with no integrity or availability consequence, placing it in the Low severity tier at CVSS 3.3. No public exploit code exists and no active exploitation has been confirmed - CISA's SSVC framework rates exploitation as none, automatable as no, and technical impact as partial, consistent with the low EPSS probability of 0.27% (19th percentile).
External control of file name or path (CWE-73) in Microsoft Office Word enables network-based information disclosure when a victim opens a specially crafted document, affecting Word 2016, Office 2019, LTSC 2021/2024, and Microsoft 365 Apps for Enterprise. An unauthenticated remote attacker can exploit this to coerce Word into resolving an attacker-controlled file path - likely a UNC path - causing an outbound network request that leaks sensitive data such as NTLM credentials. No active exploitation is confirmed (not listed in CISA KEV), and the EPSS score of 0.05% at the 14th percentile indicates negligible real-world exploitation activity at time of analysis.
Local file disclosure in Microsoft Word exposes sensitive files and directories to external parties when a victim opens a specially crafted document. Affected products span Microsoft Word 2016, Office 2019, Office LTSC 2021, Office LTSC 2024, and Microsoft 365 Apps for Enterprise across version ranges confirmed by NVD CPE data. No public exploit code has been identified and CISA SSVC rates exploitation as none with only partial technical impact; a vendor-released patch is available via the Microsoft Security Response Center.
Out-of-bounds read in Microsoft Office Word enables local information disclosure when a user opens a malicious document, affecting Microsoft 365 Apps for Enterprise and Office LTSC for Mac 2021/2024. The vulnerability requires user interaction (document opening) but does not require elevated privileges, with a CVSS score of 6.1 reflecting moderate severity. Microsoft has released patches addressing this issue across affected product lines.
