Forced browsing in Inaba Denki Sangyo CHOCO TEI WATCHER mini all versions allows remote attackers to read or delete data and alter settings. The browser-based viewer accepts crafted direct requests to sensitive API endpoints without enforcing its login process. Network reachability alone is sufficient; no credentials or user interaction are required, and live feeds, recordings, and configuration are exposed.
