CVE-2026-91717

Local information disclosure via missing Android authorization

Published Sep 15, 2026 · Updated Sep 15, 2026

Missing authorization in Google Chrome on Android before 153.0.8010.47 allows local users to obtain sensitive information through a co-installed app. The public record identifies only a missing authorization check in the Android build; it does not disclose the affected component or operation. A malicious app must already be installed on the same Android device, and the documented consequence is limited to reading sensitive information rather than modifying data or interrupting Chrome.
