Any easy way to fix file permissions?

[AtFreezingPoint]

Due to a script malfunctioning on super-user, i'm now stranded with broken permissions on the server; i can get the docker container working but the appdata folder is surely ever so slightly fucked up, any ideas on how i can easily manage to get that working?
