Improper control of generation of code ('code injection') in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Code injection (CWE-94) in Microsoft Edge (Chromium-based) enables network-based spoofing attacks against users who interact with attacker-controlled content. An unauthorized remote attacker can exploit improper code generation controls to inject and execute code within the browser's execution context, crossing security scope boundaries (S:C) to spoof content or interfaces presented to the victim. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires active user interaction: the victim must visit a malicious URL or click an attacker-crafted link in Microsoft Edge, as confirmed by UI:R in the CVSS vector - passive exploitation without any user action is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.1 (Medium) reflects a network-exploitable vector requiring no attacker privileges (PR:N) but mandating user interaction (UI:R), which is a meaningful exploitation barrier. … 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 | Apply the official Microsoft security update for Edge (Chromium-based) as documented in the MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-65804. … Detailed patch versions, workarounds, and compensating controls in full report. |
