CVE-2026-66832Network attack vector

Session-token disclosure via WebView URL parameters

Published Aug 11, 2026 · Updated Aug 11, 2026

Sensitive-data exposure in Mira Android App 4.5.15.4 allows remote attackers to obtain live session tokens through WebView requests. The in-app WebView URL builder appends a live session token to the query string and adds a persistent user identifier to the User-Agent header, exposing both to destination sites, referrer logs, and WebView JavaScript. Opening affected WebView content is required; CISA also lists Mira Hormone Monitor Firmware 1.7.1.47 as affected without explaining its role in this mechanism.
