CVE-2026-92861

API key disclosure via embedded client credential

Published Oct 8, 2026 · Updated Oct 8, 2026

Hard-coded credentials in Wavedash Co., Ltd. Ticket Ryutsu Center 4.1.9 and earlier allow local users to extract an API key from the Android app. The application embeds a key used with an external service in its client code; the specific file and extraction method have not been published. Access to a vulnerable app package exposes the key, although the developer reports that the old key has been deactivated and cannot be abused.
