🟠 High | Source: Microsoft Security Response Center A out-of-bounds read vulnerability (CVE-2026-14406) has been identified in V8, the JavaScript engine used by Chromium-based browsers. Microsoft Edge inherits this flaw from its Chromium foundation and is affected. Out-of-bounds read vulnerabilities can allow attackers to leak sensitive memory contents or potentially facilitate further exploitation if chained with other weaknesses. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest Chromium-based release across all managed endpoints and virtual desktop environments — particularly relevant for cloud workstations, Azure Virtual Desktop deployments, and any browser-based access to cloud management consoles. Validate your patch compliance via Intune or your endpoint management tooling. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in the V8 JavaScript engine (CVE-2026-14405) involves the use of uninitialized memory, which can be exploited to execute arbitrary code or cause unpredictable behaviour within the browser. This affects Microsoft Edge as it is built on the Chromium codebase and inherits the same flaw. Google has issued a fix via Chrome Releases, and Microsoft Edge will receive the patch through its Chromium ingestion process. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability (CVE-2026-14404) has been identified in PDFium, the PDF rendering library used within Chromium-based browsers, involving an inappropriate implementation. Microsoft Edge inherits this flaw from its Chromium foundation and is therefore affected. Whilst full technical details are held by Google, inappropriate implementation flaws in PDF handling can expose users to malicious content-based attacks. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest stable release across your organisation’s endpoints and virtual desktop environments, including Azure Virtual Desktop deployments. If you manage browser policies centrally via Intune or Group Policy, prioritise pushing the Chromium update and verify compliance reporting reflects the patched version. ...

🟠 High | Source: Microsoft Security Response Center A use-after-free vulnerability in Chrome’s V8 JavaScript engine (CVE-2026-14403) has been patched by Google and is being addressed in Microsoft Edge due to its shared Chromium codebase. Use-after-free flaws occur when a programme continues to use memory after freeing it, which attackers can exploit to run arbitrary code. This is particularly relevant in enterprise environments where Edge is used to access Azure and other cloud management portals. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability (CVE-2026-14402) involving uninitialized memory use has been identified in ANGLE, the graphics abstraction layer used by Chromium-based browsers. Microsoft Edge is affected as it is built on the Chromium engine. Uninitialized use vulnerabilities can potentially be exploited to leak sensitive memory contents or achieve code execution, depending on how they are triggered. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest stable release across all managed endpoints and virtual desktop environments — particularly any Azure Virtual Desktop or Dev Box deployments. Enforce browser auto-update policies via Intune or Group Policy and verify compliance through endpoint management dashboards. ...

🟠 High | Source: Microsoft Security Response Center A out-of-bounds write vulnerability (CVE-2026-14400) has been identified in ANGLE, the graphics layer abstraction library used by Chromium-based browsers. Microsoft Edge inherits this flaw from the upstream Chromium project, meaning unpatched Edge installations could be exposed. Out-of-bounds write flaws of this nature can potentially be exploited to execute arbitrary code in the context of the browser process. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest stable release across all managed endpoints and virtual desktop environments, including Azure Virtual Desktop deployments. Where browser update policies are enforced via Intune or Group Policy, verify that the latest Chromium-based Edge build incorporating Google’s patch has been distributed and confirm compliance via endpoint telemetry. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability tracked as CVE-2026-14399 has been identified in Dawn, the open-source WebGPU implementation used by Chromium. The flaw involves uninitialized memory use, which can potentially be exploited to leak sensitive data or achieve code execution within the browser. Microsoft Edge, being Chromium-based, is affected and will receive a fix via its regular Chromium ingestion process. Security Architect’s Take: Ensure Microsoft Edge deployments across your organisation are updated to the latest version as soon as Microsoft releases the patched Chromium-based build. If your environment uses browser-based access to Azure or other cloud consoles, prioritise this update to reduce the risk of in-browser exploitation targeting cloud sessions. ...

🟠 High | Source: Microsoft Security Response Center A use-after-free vulnerability (CVE-2026-14398) has been identified in ANGLE, the graphics layer used by Chromium-based browsers including Microsoft Edge. Use-after-free flaws occur when a programme continues to reference memory after it has been freed, potentially allowing an attacker to execute arbitrary code. This affects any environment where Microsoft Edge or other Chromium-based browsers are in use, including cloud-connected workstations and virtual desktop infrastructure. ...

🟠 High | Source: Microsoft Security Response Center A high-severity out-of-bounds write vulnerability (CVE-2026-14395) has been identified in V8, the JavaScript engine used by Chromium-based browsers. Microsoft Edge is affected as it is built on Chromium, and a fix has been delivered via the upstream Chrome release. Out-of-bounds write flaws in browser engines can potentially allow attackers to execute arbitrary code on a victim’s machine by tricking them into visiting a malicious webpage. ...

🟠 High | Source: Microsoft Security Response Center A use-after-free vulnerability in V8, the JavaScript engine used by Chromium-based browsers, has been assigned CVE-2026-14394. This class of memory corruption flaw can potentially allow an attacker to execute arbitrary code within the browser process, typically by luring a user to a malicious web page. Microsoft Edge inherits this vulnerability from its Chromium base and is addressed via the upstream Chrome patch. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest stable release across all managed endpoints and virtual desktop environments, including Azure Virtual Desktop deployments. Validate that your endpoint management policies (Intune or equivalent) enforce automatic browser updates and consider blocking outdated Edge versions via conditional access controls. ...
