Technical details

A relative path traversal vulnerability (CWE-23) exists in Microsoft Edge for Android. The flaw allows an attacker with local access to the device to navigate outside of intended directory restrictions by using specially crafted file paths. Successful exploitation enables the unauthorized disclosure of sensitive information from the local file system. The vulnerability is addressed in versions 150.0.4078.48 and later. No user interaction or elevated privileges are required for exploitation, though the attacker must have local access to the device.
