CVE-2024-3130

Sensitive-data exposure via decompilation-recovered embedded key

Published Apr 1, 2024 · Updated Aug 27, 2025

Hard-coded credentials in CoolKit eWeLink before 5.4.x on Android and iOS allow local users to access sensitive data. The app embeds a decryption key and algorithm that decompilation reveals, allowing protected app data to be decrypted outside the intended trust boundary. Exploitation requires high local privileges; the reported impact affects data confidentiality and integrity without interrupting service.
