Semgrep/Bandit still flag several core urllib.request.urlopen call sites even though many already validate HTTP(S) locally.

Source report: /mnt/DATA/git/govoplan/audit-reports/govoplan-full-20260713-1949

Observed locations:

  • src/govoplan_core/core/configuration_packages.py
  • src/govoplan_core/core/module_installer.py
  • src/govoplan_core/core/module_license.py
  • src/govoplan_core/core/module_package_catalog.py

Acceptance criteria:

  • Introduce a small shared safe HTTP fetch helper in core.
  • Enforce absolute http:// or https:// URL, host presence, and no embedded credentials.
  • Provide timeout and clear error mapping.
  • Replace scattered local validation where practical.
  • Add narrow scanner suppressions only on the helper, not at every call site.

Codex State: done

Summary

  • Added shared validated HTTP(S) fetch helper under govoplan_core.security.http_fetch.
  • Moved module package catalog, module license, configuration package catalog, and installer health checks onto the helper so urlopen is centralized and suppressions are local.
