AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Network-delivered spoofing with no attacker privileges; user must interact; impact is confidentiality-only with no integrity or availability effect consistent with a spoofing primitive.

External control of file name or path in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Spoofing via external file path control in Microsoft Edge (Chromium-based) enables a network-based, unauthenticated attacker to deceive users about the origin or content of resources rendered by the browser. The CVSS score of 6.5 (Medium) reflects a network-reachable attack requiring user interaction but no attacker privileges, with high confidentiality impact and no integrity or availability impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim running Microsoft Edge (Chromium-based) to actively visit or interact with attacker-controlled web content - the UI:R metric confirms mandatory user interaction, meaning passive or background exploitation is not possible under this model. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) positions this as a moderate spoofing risk: no attacker privileges are needed and complexity is low, but mandatory user interaction constrains fully automated mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to apply the vendor-released patch documented in the Microsoft MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-66324; the exact patched version number is not independently confirmed in the provided data and must be verified directly from that advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
