Insufficient ui warning of dangerous operations in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Insufficient UI warning of dangerous operations in Microsoft Edge (Chromium-based) before version 150.0.4078.48 enables network-based spoofing attacks against users who interact with adversary-controlled content. Per the CVSS vector (PR:N, UI:R), an unauthenticated remote attacker can exploit this flaw without any privileges, but requires the victim to interact with the browser during the attack. …

Vulnerability AssessmentAI
| Exploitation | The victim must be running Microsoft Edge (Chromium-based) on a version prior to 150.0.4078.48. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (Medium) reflects a network-reachable, low-complexity attack requiring no privileges but mandating user interaction (UI:R), with only limited confidentiality impact (C:L) and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious webpage and lures the victim into visiting it via a phishing link or malvertising. When the victim interacts with the page in an unpatched version of Microsoft Edge, the browser triggers a dangerous operation (such as a download, permission grant, or cross-origin navigation) without displaying the expected security warning, causing the victim to proceed unaware. … |
| Remediation | Upgrade Microsoft Edge (Chromium-based) to version 150.0.4078.48 or later; this is the vendor-released patch confirmed by EUVD-2026-41597 and the Microsoft MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-58597. … Detailed patch versions, workarounds, and compensating controls in full report. |
