Description
An issue was discovered in KaiOS 3.0 and 3.1. The binary /system/kaios/api-daemon exposes a local web server on *.localhost with subdomains for each installed applications, e.g., myapp.localhost. An attacker can make fetch requests to api-deamon to determine if a given app is installed and read the manifest.webmanifest contents, including the app version.
