CVE-2022-39873

Secret Mode bookmark modification via missing authentication

Published Oct 7, 2022 · Updated Aug 3, 2024

Improper authorization in Samsung Internet before 18.0.4.14 allows physically proximate attackers to add Secret Mode bookmarks without authentication. The Secret Mode bookmark path accepts bookmark creation without enforcing the mode's authentication check. Physical possession of an affected device is required, and the demonstrated consequence is unauthorized modification of private-browsing state.
