On the one hand, it appears to be a bug. On the other, I don't think it's a bug in nginx. The FastCGI is just receiving the variables over the socket, including SCRIPT_FILENAME. It would therefore be a bug in the program receiving from the CGI side (I'm guessing PHP?). By the way, SCRIPT_FILENAME is not a standard CGI meta-variable.

4.1. Request Meta-Variables

Meta-variables contain data about the request passed from the server
to the script, and are accessed by the script in a system-defined
manner. Meta-variables are identified by case-insensitive names[.]
