CVE-2024-23453

External-service access via embedded API key

Published Jan 23, 2024 · Updated Jun 4, 2025

Hard-coded credentials in Spoonlabs Japan Spoon 7.11.1 through 8.6.0 allow local users to extract an external-service API key. The Android application binary embeds the API key directly, exposing it when the package is reverse-engineered. Possession of the application binary is sufficient; the recovered key grants unexpected access to the associated service, while Spoon users are not directly affected.
