Severity by source
AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:H/A:N
Network spoofing needs victim to view attacker content (UI:R) under difficult conditions (AC:H); impact is integrity/trust (I:H) with a cross-origin scope change, no real confidentiality or availability loss.
Primary rating from Vendor (microsoft).

Improper access control in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Spoofing in Microsoft Edge (Chromium-based) lets a remote, unauthenticated attacker bypass an origin/security-context access control (CWE-284) to misrepresent trusted content or UI over a network. The flaw carries CVSS 8.1 with a scope-changed vector and high integrity impact, meaning a successful spoof can influence resources beyond the initially vulnerable component. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation is remote and unauthenticated (PR:N, UI:N) but gated by High attack complexity (AC:H), meaning success depends on specific timing, state, or environmental conditions rather than a single reliable request - this materially limits real-world reliability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed and should temper the raw 8.1 score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or injects a crafted web page and lures a victim to it (or wins a race/timing condition consistent with AC:H) so the browser mishandles an access-control boundary and renders attacker content as if it originated from a trusted origin or UI element. The victim is deceived into trusting spoofed content - for example a forged origin indicator or overlaid interface - potentially leading to credential or interaction phishing. … |
| Remediation | Patch available per vendor advisory: update Microsoft Edge (Chromium-based) to the fixed build published by Microsoft at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-58282 (the exact fixed version is not stated in the provided data and should be read from that advisory). … Detailed patch versions, workarounds, and compensating controls in full report. |
