dify - 💡(How to fix) Fix [SECURITY] CRITICAL: Empty SECRET_KEY + default credentials across .env.example (CWE-798)

so i was setting this up and noticed the .env.example ships with SECRET_KEY empty and almost every service password set to difyai123456 (db, redis, weaviate, chroma, qdrant, the whole lot)

i know its just an example file but people ship this, like they copy paste and forget. the flask SECRET_KEY being empty means anyone can forge sessions if it gets deployed like that

also the plugin daemon key and sandbox api key are hardcoded in both the env and the compose file, same strings in every install. if someones sandbox port ends up exposed those keys are the only thing protecting it

the ssrf proxy thing in the compose is nice btw

would be cool if the app just refused to start when SECRET_KEY is blank, with a hint to run openssl rand -hex 32. and maybe swap difyai123456 for something obviously fake like CHANGE_ME or just leave them blank so it fails loud
