Microsoft Edge (Chromium-based) Spoofing Vulnerability
AnalysisAI
Spoofing in Microsoft Edge (Chromium-based) prior to version 150.0.4078.48 allows a remote unauthenticated attacker to present deceptive browser UI to a victim user, resulting in high-confidentiality-impact information disclosure. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) confirms exploitation is network-delivered and requires only a single user interaction, consistent with a classic UI-spoofing or URL-spoofing class of flaw. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim user be running an unpatched version of Microsoft Edge (Chromium-based) below 150.0.4078.48 and must actively interact with attacker-controlled web content (UI:R), such as clicking a link or navigating to a malicious page. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (Medium) reflects a moderate but real risk profile: network-reachable (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R), which materially reduces weaponization potential compared to fully passive exploits. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious web page that exploits the spoofing flaw to render a convincing imitation of a trusted site's login prompt or security dialog within the Edge browser chrome. The attacker delivers the link via phishing email or a compromised ad network; when the victim clicks the link and interacts with the page (satisfying the UI:R requirement), the spoofed interface captures sensitive credentials or tokens. … |
| Remediation | Upgrade Microsoft Edge (Chromium-based) to version 150.0.4078.48 or later; this is the vendor-confirmed patched release per EUVD-2026-41598 and the Microsoft Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-45489. … Detailed patch versions, workarounds, and compensating controls in full report. |
