Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Network-reachable XSS needs no auth (PR:N) but requires the victim to interact (UI:R); spoofing yields limited integrity/confidentiality impact (I:L/C:L), with a scope change from the browser sandbox (S:C).
Primary rating from Vendor (microsoft).

Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Cross-site scripting in Microsoft Edge (Chromium-based) before version 150.0.4078.48 lets a remote attacker trick a victim into rendering attacker-controlled script that spoofs UI or content over the network. Because the CVSS scope is changed (S:C) and user interaction is required (UI:R), a lured user visiting or interacting with a malicious page can be deceived into trusting forged content, undermining browser security-context integrity. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively use a vulnerable Edge build (any version below 150.0.4078.48) and to perform user interaction (UI:R) - such as visiting or clicking within an attacker-controlled web page; it cannot be triggered silently without the victim's action. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are moderately consistent but not alarming. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious web page that abuses the rendering flaw so that injected script executes in a privileged or cross-origin context, then lures a victim (via phishing link or malvertising) to visit it. When the user interacts with the page, the browser renders spoofed content - for example a forged address bar or trusted-looking dialog - deceiving the victim into disclosing credentials or trusting fraudulent content. … |
| Remediation | Vendor-released patch: update Microsoft Edge (Chromium-based) to version 150.0.4078.48 or later, per Microsoft's advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-58298. … Detailed patch versions, workarounds, and compensating controls in full report. |
