Technical details
An improper access control vulnerability (CWE-284) exists in Microsoft Edge (Chromium-based) for Android. The flaw allows a remote, unauthenticated attacker to bypass security features by leveraging a network-based attack vector. Exploitation requires a user to interact with a malicious link or site (UI:R). Successful exploitation could result in high confidentiality impacts, allowing the attacker to access information that should be protected by the browser's security boundaries. The issue is addressed in version 150.0.4078.48 and later.
