CVE-2023-0654

UI spoofing via unrestricted Android task behavior

Published Aug 29, 2023 · Updated Sep 30, 2024

Tapjacking in Cloudflare WARP Mobile Client before 6.29 for Android allows local users to spoof the WARP interface. A missing UI-layer security policy lets an installed malicious application control Android task behavior and display its screen as though it were WARP. Exploitation requires that application to be installed and the victim to interact with the deceptive screen; the advisory does not specify the resulting actions.
