🟠 High | Source: Microsoft Security Response Center CVE-2026-14428 is a vulnerability in Dawn, the open-source WebGPU implementation used by Chromium-based browsers, caused by insufficient validation of untrusted input. Microsoft Edge inherits this flaw through its Chromium dependency and has addressed it via an upstream patch from Google Chrome. Unpatched browsers could potentially be exploited through malicious web content to execute unintended actions at the GPU/rendering layer. Security Architect’s Take: Ensure Microsoft Edge and any Chromium-based browsers deployed across your organisation are updated to the latest stable release. If you manage browser versions centrally via Intune, SCCM, or Group Policy, prioritise pushing this update — particularly for users accessing sensitive cloud management portals or internal web applications. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability (CVE-2026-13777) has been identified in the Chromium engine affecting input validation within the iOS web component. Because Microsoft Edge is built on Chromium, it inherits this flaw and is also affected. Google has issued a fix via Chrome, and Microsoft Edge will receive the patch through 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 the patched Chromium build is ingested. If your environment uses managed browser policies via Intune or Group Policy, verify auto-update is enabled and consider pushing an expedited update cycle for endpoints where Edge is used to access sensitive cloud workloads. ...

🟠 High | Source: Microsoft Security Response Center A memory safety vulnerability (out of bounds write) has been identified in ANGLE, the graphics abstraction layer used by Chromium-based browsers including Microsoft Edge. The flaw was assigned and patched by Google Chrome, with Microsoft Edge inheriting the fix via its Chromium dependency. Out of bounds write vulnerabilities can potentially be exploited to execute arbitrary code on a victim’s machine. Security Architect’s Take: Ensure Microsoft Edge and any Chromium-based browsers deployed across your organisation are updated to the latest version immediately. If you manage browser versions centrally via Intune, SCCM, or Group Policy, trigger an expedited update cycle and verify compliance, particularly for privileged users and developers with access to cloud management consoles. ...

🟠 High | Source: Microsoft Security Response Center A out-of-bounds read vulnerability (CVE-2026-14396) has been identified in ANGLE, the graphics abstraction layer used by Chromium-based browsers. Microsoft Edge inherits this flaw from the underlying Chromium engine, meaning unpatched versions of Edge are potentially exposed. Out-of-bounds read vulnerabilities can be exploited to leak sensitive memory contents or, in certain conditions, facilitate further exploitation. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest Chromium-based release across all managed endpoints and virtual desktop environments, including Azure Virtual Desktop deployments. Validate that your endpoint management policies (e.g. Intune, WSUS) are enforcing browser updates promptly, particularly on devices with access to sensitive cloud management portals. ...

🟠 High | Source: Microsoft Security Response Center A use-after-free vulnerability (CVE-2026-13778) has been identified in the WebUSB component of Chromium, the open-source browser engine underpinning Microsoft Edge. Use-after-free flaws occur when a programme continues to reference memory after it has been freed, which attackers can exploit to execute arbitrary code or crash the application. Microsoft Edge receives this fix via its Chromium ingestion, and users should update their browser promptly. ...

🟠 High | Source: Microsoft Security Response Center CVE-2026-14401 is a vulnerability in ANGLE, the graphics abstraction layer used by Chromium-based browsers, caused by insufficient validation of untrusted input. Microsoft Edge inherits this flaw from its Chromium foundation and is affected until patched. Such input validation weaknesses in graphics processing components can potentially be exploited to execute arbitrary code or compromise the browser sandbox. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest Chromium-based release across all managed endpoints and virtual desktop environments; prioritise this in organisations where Edge is used to access Azure portals or cloud management consoles, as browser-level exploits can serve as an initial access vector into cloud environments. ...

🟠 High | Source: Microsoft Security Response Center CVE-2026-14412 is a vulnerability in ANGLE (Almost Native Graphics Layer Engine), the graphics abstraction layer used by Chromium-based browsers including Microsoft Edge. The flaw involves insufficient validation of untrusted input, which could allow an attacker to exploit the graphics rendering pipeline via a malicious web page. Microsoft Edge is affected as it inherits this vulnerability from its Chromium foundation, and a patch has been issued via the Chromium project. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability (CVE-2026-14410) has been identified in Skia, the graphics rendering library used by Chromium-based browsers, involving an inappropriate implementation that could be exploited by malicious actors. Microsoft Edge, which is built on Chromium, is affected and has ingested the upstream fix from Google Chrome. The vulnerability originates from the Chromium project and is tracked and patched by Google. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest version across your organisation’s endpoints, particularly on machines used to access Azure portals or cloud management consoles, as browser-based vulnerabilities can be leveraged to compromise cloud sessions. Enforce browser auto-update policies via Intune or Group Policy to reduce exposure windows. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability (CVE-2026-14409) has been identified in the V8 JavaScript engine used by Chromium, affecting Microsoft Edge due to its Chromium-based architecture. The flaw relates to an inappropriate implementation within V8, which could potentially be exploited via malicious web content. Microsoft is tracking the issue but defers to Google’s Chrome release notes for full technical details. 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. Prioritise patching for users with privileged access to cloud consoles, as browser-based exploits targeting V8 can lead to session hijacking or credential theft. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability has been identified in the V8 JavaScript engine used by Chromium, tracked as CVE-2026-14407, involving an inappropriate implementation that could potentially be exploited by attackers. Microsoft Edge, being Chromium-based, inherits this flaw and is affected until patched. Google has addressed the issue in Chrome, and Microsoft is incorporating the fix into Edge via its standard Chromium ingestion process. Security Architect’s Take: Ensure Microsoft Edge is updated to the latest version across all managed endpoints and virtual desktop environments, including Azure Virtual Desktop deployments. Enforce browser update policies via Intune or Group Policy to minimise exposure windows for Chromium-based vulnerabilities. ...
