CVE-2023-26316Network attack vector

Cookie theft via JavaScript-scheme WebView allowlist bypass

Published Aug 2, 2023 · Updated Sep 27, 2024

Cross-site scripting in Xiaomi Cloud before 1.12.0.0.25 allows remote attackers to steal account cookies through a crafted URL. The application's WebView whitelist accepts the javascript URL scheme, so attacker-controlled script content loads in the trusted cloud-service context. Exploitation requires user interaction with content opened by the affected application and exposes Xiaomi Cloud session cookies.
