CVE-2025-47967: Microsoft Edge Auth Bypass Vulnerability

CVE-2025-47967 Overview

CVE-2025-47967 is a spoofing vulnerability in Microsoft Edge for Android caused by insufficient user interface warnings during dangerous operations [CWE-357]. An unauthorized attacker can exploit the flaw over a network to mislead users into performing actions they did not intend. Exploitation requires user interaction and results in a scope change, affecting resources beyond the vulnerable component. The vulnerability primarily impacts integrity, with no direct effect on confidentiality or availability. Microsoft published the advisory on September 16, 2025, and the record was last modified on June 17, 2026.

Critical Impact
Attackers can craft network-delivered content that abuses missing UI warnings in Microsoft Edge for Android to spoof trusted interface elements and deceive users into unsafe actions.

Affected Products

Microsoft Edge for Android (as identified by cpe:2.3:a:microsoft:edge:*:*:*:*:*:android:*:*)
Mobile browser deployments relying on Edge as the default browser on Android
Enterprise-managed Android devices using Microsoft Edge

Technical Details for CVE-2025-47967

Vulnerability Analysis

The vulnerability resides in the way Microsoft Edge for Android surfaces warnings when the user is about to perform a dangerous operation. The browser fails to present sufficient UI cues, allowing an attacker-controlled page to blend into or mimic trusted browser chrome. The Common Weakness Enumeration classifies this class of issue as CWE-357: Insufficient UI Warning of Dangerous Operations. Because the attack crosses the boundary between attacker-supplied web content and the browser interface, the exploit results in a scope change and impacts integrity.

Root Cause

The root cause is a missing or inadequate security prompt in the Edge for Android interface. When the browser processes attacker-controlled content that triggers a sensitive operation, no clear warning distinguishes attacker content from trusted browser UI. Users therefore cannot reliably evaluate the risk of the pending operation. This category of defect is characteristic of address-bar spoofing, dialog spoofing, and download prompt manipulation on mobile browsers.

Attack Vector

Exploitation is network-based and requires user interaction. An attacker hosts a crafted web page or delivers a link through phishing, messaging, or malvertising. When the target opens the link in Microsoft Edge for Android, the page manipulates UI elements to imitate legitimate browser behavior. The user is then tricked into approving an action such as visiting a spoofed origin, entering credentials, or accepting content that appears to come from a trusted source.

No verified public proof-of-concept code is available for this issue. Refer to the Microsoft Security Update CVE-2025-47967 advisory for vendor-supplied technical details.

Detection Methods for CVE-2025-47967

Indicators of Compromise

Mobile user reports of Edge address bar or dialog content that does not match the visited URL
Outbound connections from Android devices to newly registered or typosquatted domains referenced by phishing campaigns
Credential submissions from mobile Edge sessions to domains that differ from the displayed origin

Detection Strategies

Correlate mobile browser telemetry with threat intelligence feeds tracking phishing infrastructure abusing browser UI spoofing techniques.
Inspect enterprise proxy logs for Android Edge user-agent strings visiting low-reputation URLs immediately before authentication events.
Alert on installations of Microsoft Edge for Android versions predating the CVE-2025-47967 fix on managed devices.

Monitoring Recommendations

Ingest mobile device management (MDM) inventory data to track Edge for Android version compliance across the fleet.
Monitor identity provider logs for authentication anomalies originating from Android Edge sessions, such as unusual geolocation or new-device sign-ins.
Use behavioral AI-driven mobile protection, such as Singularity Endpoint, which protects mobile devices from zero-day malware, phishing, and man-in-the-middle attacks, to identify suspicious activity following spoofing attempts.

How to Mitigate CVE-2025-47967

Immediate Actions Required

Update Microsoft Edge for Android to the latest version available in Google Play as referenced by the Microsoft Security Response Center advisory.
Push the updated Edge build to managed Android devices through MDM policy to ensure rapid remediation.
Reinforce user awareness training focused on mobile phishing and browser UI manipulation.

Patch Information

Microsoft has issued guidance for CVE-2025-47967 through the Microsoft Security Response Center. Administrators should consult the Microsoft Security Update CVE-2025-47967 advisory for the fixed version number and rollout instructions for Microsoft Edge on Android.

Workarounds

Restrict access to unknown or untrusted links on managed Android devices using mobile threat defense policies.
Enforce URL filtering at the network or DNS layer to block known phishing domains before they reach the mobile browser.
Advise users to verify sensitive actions, such as authentication or downloads, by manually inspecting the full URL rather than trusting on-page UI elements.
