CVE-2021-43512

API-key disclosure via embedded client credentials

Published May 31, 2022 · Updated Aug 4, 2024

Insecure storage in Flightradar24 8.9.0, 8.10.0, and 8.10.2 through 8.10.4 for Android allows local users to extract API keys. The compiled Android package contains API keys in a form exposed by application decompilation rather than protecting them outside distributed client code. Local access to the application package is required, and the reported consequence is key disclosure; no integrity or availability impact is reported.
