Information disclosure in Microsoft Edge for Android allows local users to read sensitive data after user interaction. Microsoft has not disclosed the affected component or the operation that exposes the data, and the public record supplies no affected version boundary. Exploitation requires low-privileged local access and victim interaction; the reported consequence is disclosure only, with no integrity or availability impact.
