CVE-2022-28799Public exploitNetwork attack vector

Account takeover via unvalidated WebView deeplink

Published May 30, 2022 · Updated Aug 3, 2024

Improper deeplink validation in TikTok for Android before 23.7.3 allows remote attackers to take over accounts through a crafted URL. The deeplink handler accepts an attacker-controlled URL and loads it in the app's WebView, where the page can invoke exposed JavaScript bridge methods. A targeted user must click the link; the page can steal authentication tokens and read or modify private videos, messages, and profile data.
