[BUG] Javascript based templates ignore flags

[YotizJ13]

Is there an existing issue for this?

• I have searched the existing issues.

Current Behavior

Hey,
Currently, when running nuclei templates which execute javascript, Nuclei ignores the proxy flag (and others, like custom-header).

For example, running the templates:
javascript/cves/2024/CVE-2024-23897.yaml
javascript/cves/2025/CVE-2025-12101.yaml (Has both javascript and HTTP)

You can run it through BurpSuite proxy for example, and see that the request does not go through it. Same for custom-header flag, it just ignores it.

Expected Behavior

The expected behavior is that the request will go through the proxy that was set via the flag, and take into consideration flags like custom headers.

Steps To Reproduce

Run nuclei -t javascript/cves/2024/CVE-2024-23897.yaml -u TARGET --proxy PROXY -H 'Custom: Header'

Relevant log output

Environment

- OS: Ubuntu 24.04
- Nuclei: v3.5.1
- Go: 1.22.2

Anything else?
