Description

AI Translation Available

Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, the SSE event server bound to 0.0.0.0:5553 on Linux/macOS by default because the platform-dependent host default in engine/flags.go:39-46 set host = '' for non-Windows, and utils.JoinHostPort('', ':5553') resolves to ':5553'. This vulnerability is fixed in 1.17.7.
