Remote code execution in Microsoft Office Word (Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, and the corresponding macOS builds) allows an unauthenticated attacker to run arbitrary code in the security context of a victim who opens a specially crafted document. The flaw is a heap-based buffer overflow reachable over the network, and because it requires only low attack complexity and no privileges (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 8.8), the sole barrier to exploitation is the user-interaction requirement - the victim must open the malicious Word file, which is the primary limiting factor. No public exploit code has been identified at time of analysis, and there is no confirmed actively exploited (CISA KEV) status, but Microsoft has published a vendor patch, so this should be treated as a genuine high-priority, patch-now item rather than an emergency.
Remote code execution in Microsoft Outlook is possible through a heap-based buffer overflow that an unauthenticated, network-based attacker can trigger by convincing a victim to open or preview a crafted email message or Office document. The vulnerability affects Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, and Office 365 for Mac, but a vendor patch is available. Exploitation carries a high attack complexity due to required heap grooming and memory-layout control, and no public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.
Remote code execution in Microsoft Excel is possible when a user opens or previews a specially crafted spreadsheet, which triggers a use-after-free during file parsing and lets an unauthenticated attacker run code in the context of the victim. The flaw carries a CVSS of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) and affects Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, the Mac LTSC and Office 365 for Mac builds, and Office Online Server, with no attacker authentication required but mandatory user interaction (UI:R) - meaning successful exploitation depends on social engineering rather than automatic server-side triggering, and Protected View plus Mark-of-the-Web warnings can interrupt the chain. At time of analysis there is no confirmed active exploitation (no CISA KEV listing) and no public exploit code identified, and Microsoft has published a vendor fix via its MSRC update guide; risk is high but manageable through prompt patching and the existing Office security defaults.

Vendor-released patch available through Microsoft security updates.
An out-of-bounds memory read in Microsoft PowerPoint lets remote attackers leak information from the memory of the affected Office process when a user opens a specially crafted presentation file. The flaw carries a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), meaning confidentiality is heavily impacted while integrity and availability are untouched, and it affects Microsoft 365 Apps for Enterprise, Office 365 for Mac, and Office LTSC 2021/2024 on both Windows and macOS. No public exploit has been identified at time of analysis, but the attack path is straightforward: an unauthenticated attacker only needs to convince a victim to open a malicious .ppt/.pptx file, so email and web-delivered documents remain the primary delivery vector. A vendor patch is available through Microsoft's update guide.
An information disclosure vulnerability in Microsoft PowerPoint allows a remote, unauthenticated attacker to trigger an out-of-bounds memory read by convincing a victim to open a specially crafted presentation file, potentially exposing heap contents that may contain sensitive data. Affected builds span Microsoft 365 Apps for Enterprise, Office 365 for Mac, and the Office LTSC 2021 and 2024 releases on both Windows and macOS. The attacker needs no credentials (PR:N), but the attack hinges entirely on user interaction (UI:R) - the document must be opened, and Protected View or Mark-of-the-Web handling for externally sourced files can interrupt the chain. Microsoft has released a vendor patch and no public exploit code or active exploitation has been identified at time of analysis.
Opening a specially crafted PowerPoint document in an unpatched Microsoft Office build can trigger an out-of-bounds read that leaks the contents of process memory to the attacker. Affected builds include Microsoft 365 Apps for Enterprise, Office LTSC 2021 and 2024, and the corresponding Office for Mac / LTSC for Mac 2021 and 2024 clients; exploitation is remote and needs no credentials (AV:N/PR:N) but hinges entirely on user interaction (UI:R), since the victim must open or preview the malicious file. The result is read-only memory disclosure (C:H, I:N, A:N) rather than code execution or data tampering, and there is no public exploit identified at time of analysis, though a vendor patch is available per the Microsoft Security Response Center advisory.
Information disclosure in Microsoft Word allows a remote, unauthenticated attacker to read memory contents from an affected Office installation by getting a user to open or preview a maliciously crafted Word document delivered over the network, such as an email attachment or a download. The flaw is a use-after-free (CWE-416) that is present in Microsoft 365 Apps for Enterprise and in Microsoft Office 365 for Mac, Office LTSC for Mac 2021, and Office LTSC for Mac 2024; per the CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) the impact is limited to confidentiality, with no code execution, integrity, or availability effect. This is a moderate-priority issue rather than a critical one: exploitation is gated by the mandatory UI:R user-interaction requirement, and no confirmed active exploitation (CISA KEV) or publicly available exploit code was identified at time of analysis; a vendor patch is available via the Microsoft Security Response Center advisory.
An out-of-bounds read in Microsoft Word (CWE-125) lets remote, unauthenticated attackers disclose the contents of process memory when a victim opens a specially crafted document, with affected builds spanning Microsoft 365 Apps for Enterprise, Office 365 for Mac, Office LTSC 2021/2024, and Office LTSC for Mac 2021/2024. Exploitation requires the user to open the malicious file (UI:R) and deliver it successfully through social engineering, so it is not a zero-click or wormable flaw, and the impact is limited to information disclosure (C:H, I:N, A:N) without code execution or persistence. No public exploit code has been identified at time of analysis, and Microsoft has published a vendor patch through its update guide.
Information disclosure in Microsoft Word (and the broader Microsoft 365 Apps for Enterprise, Office 365 for Mac, and Office LTSC 2021/2024 families) allows a remote attacker to read memory contents from the affected application by convincing a victim to open a specially crafted document. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N): the attacker needs no authentication, but exploitation hinges on user interaction - the target must open the malicious file - so delivery depends on phishing or social engineering rather than automatic remote compromise. Impact is limited to confidentiality (no code execution, integrity, or availability effect) and remains confined to the vulnerable process; there is no public exploit identified at time of analysis and no evidence of confirmed active exploitation, though the disclosure of high-value memory contents can still expose sensitive document data or session material. Microsoft has published a vendor patch via its MSRC update guide.
An out-of-bounds read in Microsoft Word (CVE-2026-108434, CVSS 6.5) allows a remote, unauthenticated attacker to disclose information from process memory if the victim opens or previews a specially crafted Word document. Affected builds are Microsoft 365 Apps for Enterprise, Office LTSC 2021 and 2024 on Windows, and Office LTSC for Mac 2021/2024 plus Office 365 for Mac, per the vendor CPE list. Because the vector requires user interaction (UI:R) and the impact is limited to confidentiality (C:H with I:N/A:N), there is no zero-click or server-side exploitation path; Microsoft has published a fix through its MSRC update guide, and no public exploit code or confirmed active exploitation was identified at time of analysis, making this a moderate-priority patching item rather than an emergency.
Memory parsing across Microsoft Office and SharePoint Server products is susceptible to a CWE-125 out-of-bounds read that, when triggered by opening a specially crafted Office document, produces local information disclosure or application availability loss. The affected surface is broad - spanning Microsoft 365 Apps for Enterprise, Office 2016 through LTSC 2024 on both Windows and macOS, and SharePoint Enterprise Server 2016, 2019, and Subscription Edition - but real-world exploitation pressure is low: EPSS sits at 0.36% (28th percentile), CISA SSVC rates exploitation as none and the attack as non-automatable, and no public exploit has been identified at time of analysis. Vendor-released patches are available for all affected product lines.
Out-of-bounds read in Microsoft Office exposes sensitive memory contents to a local, unauthenticated attacker who can induce a user to open a malicious document. Affected products span the full current Office portfolio - Office 2016 through LTSC 2024 on both Windows and macOS - making the blast radius broad despite the local attack vector. No public exploit identified at time of analysis and SSVC classifies exploitation as none and not automatable, though the high confidentiality impact (C:H) and near-universal deployment of Office keep this a meaningful patching priority.
Out-of-bounds read in Microsoft Office and SharePoint exposes process memory contents locally when a user opens a specially crafted document. Affected products span the full Office suite - Office 2016, 2019, LTSC 2021, LTSC 2024, Microsoft 365 Apps for Enterprise (Windows and Mac), and SharePoint Server 2016, 2019, and Subscription Edition - covering virtually the entire active Office install base. No public exploit code exists and CISA SSVC rates exploitation as none, making this a patch-and-monitor priority rather than an emergency response.
Information disclosure in Microsoft Office (Microsoft 365 Apps, Office 2016/2019, Office LTSC 2021/2024, and Office for Mac) arises from an out-of-bounds read (CWE-125) that lets an attacker who convinces a victim to open a crafted file read memory beyond an intended buffer boundary. Exploitation is local and requires user interaction, and there is no public exploit identified at time of analysis and no CISA KEV listing. Disclosed memory can leak sensitive data such as heap contents or pointer addresses useful for defeating ASLR in a follow-on exploit chain.
Remote code execution in Microsoft Office Word (Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, and the corresponding macOS builds) allows an unauthenticated attacker to run arbitrary code in the security context of a victim who opens a specially crafted document. The flaw is a heap-based buffer overflow reachable over the network, and because it requires only low attack complexity and no privileges (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 8.8), the sole barrier to exploitation is the user-interaction requirement - the victim must open the malicious Word file, which is the primary limiting factor. No public exploit code has been identified at time of analysis, and there is no confirmed actively exploited (CISA KEV) status, but Microsoft has published a vendor patch, so this should be treated as a genuine high-priority, patch-now item rather than an emergency.
Remote code execution in Microsoft Outlook is possible through a heap-based buffer overflow that an unauthenticated, network-based attacker can trigger by convincing a victim to open or preview a crafted email message or Office document. The vulnerability affects Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, and Office 365 for Mac, but a vendor patch is available. Exploitation carries a high attack complexity due to required heap grooming and memory-layout control, and no public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.
Remote code execution in Microsoft Excel is possible when a user opens or previews a specially crafted spreadsheet, which triggers a use-after-free during file parsing and lets an unauthenticated attacker run code in the context of the victim. The flaw carries a CVSS of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) and affects Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, the Mac LTSC and Office 365 for Mac builds, and Office Online Server, with no attacker authentication required but mandatory user interaction (UI:R) - meaning successful exploitation depends on social engineering rather than automatic server-side triggering, and Protected View plus Mark-of-the-Web warnings can interrupt the chain. At time of analysis there is no confirmed active exploitation (no CISA KEV listing) and no public exploit code identified, and Microsoft has published a vendor fix via its MSRC update guide; risk is high but manageable through prompt patching and the existing Office security defaults.
Remote code execution in Microsoft Word affects Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, and Office for Mac/LTSC for Mac editions, allowing an unauthenticated attacker to execute arbitrary code by convincing a victim to open a specially crafted document (UI:R). The stack-based buffer overflow (CWE-121) requires no privileges or non-default configuration (PR:N, AC:L), making it a high-priority target for social-engineering campaigns, though no public exploit code has been identified at time of analysis. Patch available per vendor advisory from the Microsoft Security Response Center.
Heap-based buffer overflow in Microsoft Office (Windows and macOS builds: Microsoft 365 Apps for Enterprise, Office LTSC 2021/2024, and Office 365/LTSC for Mac) allows unauthenticated remote attackers to execute arbitrary code when a victim opens a crafted document. Exploitation requires user interaction (UI:R in the CVSS vector) and is not zero-click, executing with the victim user's privileges rather than SYSTEM. No public exploit has been identified at time of analysis, and a vendor patch is available per the Microsoft advisory (CVE-2026-108444).

Arbitrary code execution in Microsoft Excel (and the broader Office family through Microsoft 365 Apps, Office 2019, LTSC 2021/2024, Office for Mac, and Office Online Server) is possible when a user opens a maliciously crafted spreadsheet that triggers a heap-based buffer overflow (CWE-122), running attacker code in the context of the current user. There is no public exploit identified at time of analysis and the EPSS probability is very low (0.06%, 18th percentile), but the technical impact is total (full confidentiality, integrity, and availability loss). Microsoft has released patches; exploitation requires the victim to open a file, so it is a phishing/social-engineering-driven local vulnerability rather than a remotely wormable one.
Local code execution in Microsoft Office Word (2016, 2019, LTSC 2021/2024, Microsoft 365 Apps, and Office LTSC for Mac 2021/2024) arises from a use-after-free memory-corruption flaw that lets an attacker run arbitrary code in the context of the user who opens a maliciously crafted document. Microsoft has released a patch, and no public exploit has been identified at time of analysis; EPSS is very low at 0.06% (18th percentile) and CISA SSVC records no known exploitation.
Local code execution in Microsoft Office Excel (Excel 2016, Office 2019/LTSC 2021/2024, Microsoft 365 Apps, Office for Mac, and Office Online Server) arises from a use-after-free memory corruption flaw that an attacker triggers by convincing a user to open a specially crafted spreadsheet. Successful exploitation yields full compromise of the current user's context (high confidentiality, integrity, and availability impact). There is no public exploit identified at time of analysis, EPSS is very low (0.06%), and CISA SSVC records exploitation status as none, indicating this is a patch-in-cycle issue rather than an active threat.
Local code execution in Microsoft Office (2016, 2019, LTSC 2021/2024, 365 Apps, and Office LTSC for Mac 2021/2024) arises from a use-after-free memory corruption (CWE-416) that lets an attacker run arbitrary code with the victim's privileges. Microsoft's CVSS vector rates it AV:L/PR:N/UI:N (base 8.4) with total technical impact, though there is no public exploit identified at time of analysis and EPSS exploitation probability is negligible at 0.04%. A vendor patch is available from Microsoft (MSRC update guide).
Local code execution in Microsoft Office (LTSC for Mac 2021/2024 and Office for Android) via a heap-based buffer overflow (CWE-122) that an unauthorized attacker triggers when a victim opens a maliciously crafted document, yielding full confidentiality, integrity, and availability impact in the user's context. Exploitation requires user interaction (UI:R) and local access (AV:L), so weaponization depends on social engineering rather than remote reachability. This is no public exploit identified at time of analysis, with a very low EPSS score of 0.06% and CISA SSVC rating exploitation as 'none', indicating no observed activity despite the 'total' technical impact.
Local code execution in Microsoft Word (and the Office suites that bundle it - Office 2016/2019, LTSC 2021/2024, Microsoft 365 Apps, and Office LTSC for Mac 2021/2024) stems from a use-after-free memory-corruption defect that lets an attacker run arbitrary code in the context of the current user, typically by having the victim process a crafted document. Microsoft (the reporting party) has released a fix; there is no public exploit identified at time of analysis and EPSS is very low (0.04%, 14th percentile). SSVC rates exploitation as none but technical impact as total, so this is a patch-on-schedule item rather than an emergency.
Local code execution in Microsoft Word (Office 2016 through Office LTSC 2024, Microsoft 365 Apps, and Office for Mac) results from a type-confusion flaw (CWE-843) that lets an unauthorized attacker run arbitrary code with the victim's privileges. Microsoft rates it CVSS 8.4 with total technical impact, but there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.15%, 35th percentile). CISA SSVC records exploitation status as none and the issue is not automatable, indicating no observed in-the-wild activity.
Local code execution in Microsoft Office (2016, 2019, LTSC 2021/2024, 365 Apps for Enterprise, Office for Android, and Office LTSC for Mac 2021/2024) stems from a heap-based buffer overflow that lets an attacker run arbitrary code with the victim's privileges. The flaw was reported by Microsoft, a vendor patch is available, and there is no public exploit identified at time of analysis; EPSS is very low at 0.04% and CISA SSVC records exploitation as none. Impact is total (full confidentiality, integrity, and availability loss) but exploitation is not automatable and, per typical Office file-parsing bugs, hinges on processing attacker-supplied content.
Information disclosure in Microsoft Excel (and the broader Office family - Office 2019, Office LTSC 2021/2024, Office for Mac, Microsoft 365 Apps for Enterprise, and Office Online Server) allows an attacker to read memory beyond an allocated buffer when a victim opens a crafted spreadsheet, potentially leaking sensitive in-process data. Exploitation is local and requires user interaction (opening the malicious file); there is no public exploit identified at time of analysis and CISA SSVC scores exploitation as 'none'. EPSS is very low (0.06%, 18th percentile), indicating negligible observed exploitation activity, though the technical impact is rated 'total'.
Memory corruption in Microsoft Office Word enables local code execution through a use-after-free flaw affecting Microsoft 365 Apps for Enterprise and Office LTSC 2021/2024 for Windows and Mac. Despite the local attack vector (AV:L), the vulnerability requires no privileges (PR:N) or user interaction (UI:N), allowing unauthorized attackers to execute arbitrary code with high impact to confidentiality, integrity, and availability (CVSS 8.4). Vendor-released patch available via Microsoft Security Response Center as of April 2026. No public exploit identified at time of analysis, though the technical simplicity (AC:L) and memory corruption primitive increase weaponization risk.
Microsoft Office Word untrusted pointer dereference (CWE-822) enables local code execution with high impact across Microsoft 365 Apps for Enterprise and Office LTSC 2021/2024 editions (Windows and macOS). The vulnerability requires local access but no privileges or user interaction (CVSS:3.1/AV:L/AC:L/PR:N/UI:N), allowing unauthenticated local attackers to achieve full system compromise. Vendor-released patch available per Microsoft Security Response Center advisory. No public exploit identified at time of analysis. SSVC assessment indicates no confirmed exploitation, non-automatable attack, but total technical impact (full control).
Use-after-free memory corruption in Microsoft Office Word enables local code execution with high privileges when victims open malicious documents. Affects Microsoft 365 Apps for Enterprise and Office LTSC 2021/2024 for Windows and Mac (versions below 16.108.26041219 for Mac; click-to-run editions require latest security updates). CVSS 7.8 reflects local attack vector requiring user interaction, but exploitation grants complete system compromise (confidentiality, integrity, availability all rated High). No public exploit identified at time of analysis, though use-after-free vulnerabilities are well-understood exploitation primitives. Vendor-released patch available through Microsoft security updates.
An out-of-bounds memory read in Microsoft PowerPoint lets remote attackers leak information from the memory of the affected Office process when a user opens a specially crafted presentation file. The flaw carries a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), meaning confidentiality is heavily impacted while integrity and availability are untouched, and it affects Microsoft 365 Apps for Enterprise, Office 365 for Mac, and Office LTSC 2021/2024 on both Windows and macOS. No public exploit has been identified at time of analysis, but the attack path is straightforward: an unauthenticated attacker only needs to convince a victim to open a malicious .ppt/.pptx file, so email and web-delivered documents remain the primary delivery vector. A vendor patch is available through Microsoft's update guide.
An information disclosure vulnerability in Microsoft PowerPoint allows a remote, unauthenticated attacker to trigger an out-of-bounds memory read by convincing a victim to open a specially crafted presentation file, potentially exposing heap contents that may contain sensitive data. Affected builds span Microsoft 365 Apps for Enterprise, Office 365 for Mac, and the Office LTSC 2021 and 2024 releases on both Windows and macOS. The attacker needs no credentials (PR:N), but the attack hinges entirely on user interaction (UI:R) - the document must be opened, and Protected View or Mark-of-the-Web handling for externally sourced files can interrupt the chain. Microsoft has released a vendor patch and no public exploit code or active exploitation has been identified at time of analysis.
Opening a specially crafted PowerPoint document in an unpatched Microsoft Office build can trigger an out-of-bounds read that leaks the contents of process memory to the attacker. Affected builds include Microsoft 365 Apps for Enterprise, Office LTSC 2021 and 2024, and the corresponding Office for Mac / LTSC for Mac 2021 and 2024 clients; exploitation is remote and needs no credentials (AV:N/PR:N) but hinges entirely on user interaction (UI:R), since the victim must open or preview the malicious file. The result is read-only memory disclosure (C:H, I:N, A:N) rather than code execution or data tampering, and there is no public exploit identified at time of analysis, though a vendor patch is available per the Microsoft Security Response Center advisory.
Information disclosure in Microsoft Word allows a remote, unauthenticated attacker to read memory contents from an affected Office installation by getting a user to open or preview a maliciously crafted Word document delivered over the network, such as an email attachment or a download. The flaw is a use-after-free (CWE-416) that is present in Microsoft 365 Apps for Enterprise and in Microsoft Office 365 for Mac, Office LTSC for Mac 2021, and Office LTSC for Mac 2024; per the CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) the impact is limited to confidentiality, with no code execution, integrity, or availability effect. This is a moderate-priority issue rather than a critical one: exploitation is gated by the mandatory UI:R user-interaction requirement, and no confirmed active exploitation (CISA KEV) or publicly available exploit code was identified at time of analysis; a vendor patch is available via the Microsoft Security Response Center advisory.
An out-of-bounds read in Microsoft Word (CWE-125) lets remote, unauthenticated attackers disclose the contents of process memory when a victim opens a specially crafted document, with affected builds spanning Microsoft 365 Apps for Enterprise, Office 365 for Mac, Office LTSC 2021/2024, and Office LTSC for Mac 2021/2024. Exploitation requires the user to open the malicious file (UI:R) and deliver it successfully through social engineering, so it is not a zero-click or wormable flaw, and the impact is limited to information disclosure (C:H, I:N, A:N) without code execution or persistence. No public exploit code has been identified at time of analysis, and Microsoft has published a vendor patch through its update guide.
Information disclosure in Microsoft Word (and the broader Microsoft 365 Apps for Enterprise, Office 365 for Mac, and Office LTSC 2021/2024 families) allows a remote attacker to read memory contents from the affected application by convincing a victim to open a specially crafted document. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N): the attacker needs no authentication, but exploitation hinges on user interaction - the target must open the malicious file - so delivery depends on phishing or social engineering rather than automatic remote compromise. Impact is limited to confidentiality (no code execution, integrity, or availability effect) and remains confined to the vulnerable process; there is no public exploit identified at time of analysis and no evidence of confirmed active exploitation, though the disclosure of high-value memory contents can still expose sensitive document data or session material. Microsoft has published a vendor patch via its MSRC update guide.
An out-of-bounds read in Microsoft Word (CVE-2026-108434, CVSS 6.5) allows a remote, unauthenticated attacker to disclose information from process memory if the victim opens or previews a specially crafted Word document. Affected builds are Microsoft 365 Apps for Enterprise, Office LTSC 2021 and 2024 on Windows, and Office LTSC for Mac 2021/2024 plus Office 365 for Mac, per the vendor CPE list. Because the vector requires user interaction (UI:R) and the impact is limited to confidentiality (C:H with I:N/A:N), there is no zero-click or server-side exploitation path; Microsoft has published a fix through its MSRC update guide, and no public exploit code or confirmed active exploitation was identified at time of analysis, making this a moderate-priority patching item rather than an emergency.
Memory parsing across Microsoft Office and SharePoint Server products is susceptible to a CWE-125 out-of-bounds read that, when triggered by opening a specially crafted Office document, produces local information disclosure or application availability loss. The affected surface is broad - spanning Microsoft 365 Apps for Enterprise, Office 2016 through LTSC 2024 on both Windows and macOS, and SharePoint Enterprise Server 2016, 2019, and Subscription Edition - but real-world exploitation pressure is low: EPSS sits at 0.36% (28th percentile), CISA SSVC rates exploitation as none and the attack as non-automatable, and no public exploit has been identified at time of analysis. Vendor-released patches are available for all affected product lines.
Out-of-bounds read in Microsoft Office exposes sensitive memory contents to a local, unauthenticated attacker who can induce a user to open a malicious document. Affected products span the full current Office portfolio - Office 2016 through LTSC 2024 on both Windows and macOS - making the blast radius broad despite the local attack vector. No public exploit identified at time of analysis and SSVC classifies exploitation as none and not automatable, though the high confidentiality impact (C:H) and near-universal deployment of Office keep this a meaningful patching priority.
Out-of-bounds read in Microsoft Office and SharePoint exposes process memory contents locally when a user opens a specially crafted document. Affected products span the full Office suite - Office 2016, 2019, LTSC 2021, LTSC 2024, Microsoft 365 Apps for Enterprise (Windows and Mac), and SharePoint Server 2016, 2019, and Subscription Edition - covering virtually the entire active Office install base. No public exploit code exists and CISA SSVC rates exploitation as none, making this a patch-and-monitor priority rather than an emergency response.
Information disclosure in Microsoft Office (Microsoft 365 Apps, Office 2016/2019, Office LTSC 2021/2024, and Office for Mac) arises from an out-of-bounds read (CWE-125) that lets an attacker who convinces a victim to open a crafted file read memory beyond an intended buffer boundary. Exploitation is local and requires user interaction, and there is no public exploit identified at time of analysis and no CISA KEV listing. Disclosed memory can leak sensitive data such as heap contents or pointer addresses useful for defeating ASLR in a follow-on exploit chain.
