External control of file name or path in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in Microsoft Edge (Chromium-based) before version 150.0.4078.48 lets an unauthorized attacker run arbitrary code when a victim is lured to interact with attacker-controlled content, stemming from external control of a file name or path (CWE-73). The flaw is network-reachable but non-trivial to exploit, requiring user interaction and high attack complexity, and there is no public exploit identified at time of analysis. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running a Microsoft Edge (Chromium-based) build below 150.0.4078.48 and to actively interact with attacker-controlled web content - the CVSS vector's UI:R makes victim interaction a hard prerequisite, so this cannot be triggered silently against an idle browser. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a genuine but not top-priority issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious web page that supplies attacker-controlled input to influence a file name or path handled by Edge, then lures a victim via phishing or a malicious link into visiting it and interacting with it (e.g., clicking or confirming a prompt). Given the high attack complexity, the attacker may need to satisfy specific conditions or win a race for reliable execution, after which arbitrary code runs in the victim's context. … |
| Remediation | Vendor-released patch: update Microsoft Edge to version 150.0.4078.48 or later, which is the first fixed build per the EUVD data and Microsoft's MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-58293. … Detailed patch versions, workarounds, and compensating controls in full report. |
