Exposure of sensitive information to an unauthorized actor in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Microsoft Edge (Chromium-based) versions prior to 150.0.4078.48 expose sensitive information to unauthorized network actors, enabling spoofing attacks against users who interact with attacker-controlled content. The vulnerability maps to CWE-200, indicating that browser-internal sensitive data (likely origin, URL, or session context) is improperly disclosed across a network boundary, allowing an attacker to impersonate trusted content or identities. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required - the victim must actively navigate to or interact with attacker-controlled web content in Microsoft Edge (UI:R in CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N yields a score of 6.5, reflecting a moderate-to-notable risk profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a targeted phishing email or social-media message containing a link to an attacker-controlled webpage. When the victim opens the link in an unpatched Microsoft Edge browser, the page triggers the CWE-200 information disclosure, leaking sensitive browser data (such as origin context or session identifiers) to the attacker's server. … |
| Remediation | Upgrade Microsoft Edge (Chromium-based) to version 150.0.4078.48 or later, which contains the vendor-released patch per the MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-56646. … Detailed patch versions, workarounds, and compensating controls in full report. |
