CVE-2026-58300

Local information disclosure via absolute path traversal

Published Jul 3, 2026 · Updated Jul 3, 2026

Absolute path traversal in Microsoft Edge for Android before 150.0.4078.48 allows local users to disclose information from the device. Microsoft has not published the affected component or the path-handling operation that accepts an absolute path and resolves it outside its intended location. Exploitation requires local access to the Android device and exposes files readable through the vulnerable Edge process, with no reported write or code-execution impact.
