Unauthenticated debug-log disclosure via message_log endpoint

Published Dec 5, 2025 · Updated Jul 28, 2026

Information disclosure in affected ReQuest Serious Play F3 Media Server and Pro builds allows remote attackers to read sensitive debug logs. The unauthenticated message_log page returns the Python debug log, which records system details, credentials, paths, processes, and command arguments. Network access to the web management server is sufficient, and disclosure is limited to information already written to that log.
