CVE-2020-25900
MediumCVSS 5.3Summary
HelloTalk w wersji 3.4.1 przechowuje pełne współrzędne GPS, nawet gdy użytkownik zamierzał udostępnić jedynie kraj lub miasto. Współrzędne te są umieszczane w bazie danych na urządzeniach innych użytkowników.
Risk Assessment
Przechowywanie dokładnych współrzędnych GPS może prowadzić do naruszenia prywatności użytkowników oraz nieautoryzowanego dostępu do ich lokalizacji. To stwarza ryzyko dla bezpieczeństwa danych osobowych.
Recommendation
Zaleca się aktualizację aplikacji do najnowszej wersji, aby zminimalizować ryzyko związane z przechowywaniem danych lokalizacyjnych. Dodatkowo, warto przeanalizować politykę udostępniania lokalizacji przez użytkowników.

- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
HelloTalk through 3.4.1 stores full-precision GPS coordinates even when the user had intended to share only a country or city. Furthermore, these coordinates are placed into a database on the client of other users. (The client side was changed in 2019 to encrypt that database.)
