📄 Description

Summary

Validate each redirect target during requests-based RAG web URL ingestion instead of only validating the initial URL.
Route synchronous web-loader and binary-content preflight requests through a safe GET helper.
Add regression tests covering public URLs that redirect to private network targets.

Why

Open WebUI already blocks direct private/local URLs when local web fetch is disabled, but requests-based ingestion paths could follow redirects after the initial validation. A public URL could redirect backend ingestion to localhost, private networks, or cloud metadata endpoints.

Tests

PYTHONPATH=backend uv run pytest backend/open_webui/test/retrieval/web/test_url_validation.py -q
App smoke test: /health and /ready returned 200 {"status":true}
