[BUG] go engine doesn't work in code template

[sttlr]

Is there an existing issue for this?

• I have searched the existing issues.

Current Behavior

Nuclei code templates with engine set to go don't work.

I can change the name of go binary to anything - it doesn't matter. code template still wouldn't work when engine would be pointing to go binary.

But, I can create go file in the current directory - add it to $PATH - and code template executes successfully.

export PATH="`pwd`:$PATH"
echo -e '#!/bin/bash\necho "I am a bash script, but got executed with name go"' > go

And then, when I run the same go-code-engine.yaml it works:

I have no problem with running code templates with engine set to python3 or bash.

And yes, I do have go binary in $PATH.

Expected Behavior

Per Nuclei Template Docs - https://docs.projectdiscovery.io/templates/protocols/code#engine

To execute the code, a list of language interpreters, which are installed or available on the system environment, is specified. These interpreters can be and not limited to bash sh py python3, go, ps, among others, and they are searched sequentially until a suitable one is found. The identifiers for these interpreters should correspond to their respective names or identifiers recognized by the system environment.

Nuclei code templates with engine set to go should work just as with other engines (like python3).

Steps To Reproduce

1. Create go-code-engine.yaml:

id: go-code-engine

info:
  name: go-code-engine
  author: sttlr
  severity: info

self-contained: true
code:
  - engine:
      - go
    args:
      - run
    pattern: "*.go"
    source: |
      package main

      import "fmt"

      func main() {
          fmt.Println("hello world")
      }

    extractors:
      - type: dsl
        dsl:
          - response
      - type: dsl
        dsl:
          - stderr

2. Run nuclei -duc -code -t ./go-code-engine.yaml -v -debug -validate

Relevant log output
