## Technical details

The vulnerable Android application uses an OkHttpClient with a custom X509TrustManager that accepts all certificates and a hostname verifier that accepts any hostname, allowing network-based attackers to intercept encrypted traffic without a trusted CA. Attack requires network adjacency (CWE-295 improper certificate validation); an attacker can capture sessions and modify health data or authentication records. Fixed in version 2.8.1.0, which rejects untrusted certificates.
