Microsoft Edge Vulnerability CVE-2026-110160: Missing Authorization in Chromium
A missing authorization flaw in Chromium, incorporated into Microsoft Edge, could allow attackers to gain unauthorized access to privileged features. Edge users should apply the latest updates immediately and verify that the patch is in place. Defenders should monitor for anomalous activity and enforce least‑privilege policies.
What happened
A missing authorization flaw was discovered in the Chromium engine that powers Microsoft Edge. The vulnerability could allow an attacker to invoke privileged API calls without proper authentication.
Impact
Edge users running unpatched versions may be exposed to unauthorized access to browser features or extensions. The flaw does not directly compromise user data but can be leveraged for privilege escalation within the browser context.
Mitigation
Apply the latest Microsoft Edge update (version 120 or later). Verify that the patch is installed via the About Edge page. Disable or restrict extensions that require elevated privileges until the update is applied.
Detection
Monitor for anomalous API usage or unexpected privilege escalation events in browser logs. Use endpoint detection tools to flag repeated attempts to access privileged browser APIs.
