[FEATURE] ... Special variables like BaseURL should be accessible in flow/javascript/code protocol.

[r14s]

Describe your feature request

Currently special variables like BaseURL, Path, ... aren't accessible from flow/javascript/code protocol.
Example:

id: test
info:
  name: test
  author: test
  severity: info
flow: |
  log("{{BaseURL}}");
  log(template["BaseURL"]);
http:
  - method: GET
    path:
      - "{{BaseURL}}"

Output:

[JS] {{BaseURL}}
[JS] <nil>

Describe the use case of the feature

I've wanted to implement a CVE that needs two segments of the path to be modified.
One payload must be added before target path element.
Second payload must be inbetween the target path element.
For example:
/home/admin -> /home/PAYLOAD1/adPAYLOAD2min
I've wanted to implement it via Path and regex but Path/BaseURL aren't accessible.
