Replaced the vulnerable struct copy mechanism for URL reconstruction
in `executeRemote` with a strict `url.URL{}` struct literal. This ensures
only necessary, validated fields (`Scheme`, `Host`, `Path`, `User`, `RawQuery`)
are preserved, completely isolating the URL from unintended fields like
`Opaque` which can bypass validation during routing.

🚨 Severity: HIGH
💡 Vulnerability: Server-Side Request Forgery (SSRF) via insecure URL construction in the CLI Executor. Modifying a copied
url.URLstruct by nullifying specific fields allows bypasses if theOpaquefield is populated, asurl.URL.String()prioritizes it.🎯 Impact: An attacker could craft a payload bypassing path validations and arbitrary routing internal requests, potentially accessing internal services or bypassing proxy restrictions.
🔧 Fix: Replaced the struct copy mechanism with a strict
url.URL{}struct literal. Explicitly assigned only necessary, validated fields (Scheme,Host,Path,User,RawQuery) to completely isolate the URL reconstruction from unintended fields likeOpaque.✅ Verification: Ran
gosecscan and ensured that the vulnerable taint flow is properly terminated using a new structure.PR created automatically by Jules for task 8519806723832699938 started by @rschumann
