| summary: Output of "go env" does not sanitize values in cmd/go |
| description: |- |
| Command go env is documented as outputting a shell script containing the Go |
| environment. However, go env doesn't sanitize values, so executing its output as |
| a shell script can cause various bad bahaviors, including executing arbitrary |
| commands or inserting new environment variables. |
| |
| This issue is relatively minor because, in general, if an attacker can set |
| arbitrary environment variables on a system, they have better attack vectors |
| than making "go env" print them out. |
