CVE-2025-44017Network attack vector

JWT disclosure via crafted URL outbound request

Published Sep 2, 2025 · Updated Sep 2, 2025

Sensitive-data exposure in Gunosy App for Android and iOS before 7.34.0 allows remote attackers to obtain a user's JWT via a crafted URL. The apps include the JWT in outbound communication initiated when that crafted URL is opened; the public advisory does not identify the exact code path or field carrying it. Exploitation requires a user to open the attacker-crafted URL, and the documented consequence is disclosure of that user's authentication token.
