Orion Open Redirect Hunter

Orion Open Redirect Hunter automates manual tests for Open Redirect (Unvalidated Redirects/Forwards) in web apps.
It injects benign, controlled payloads pointing to example.com and never follows redirects. Instead, it observes:

HTTP 3xx Location headers

HTML meta refresh tags

JavaScript redirects (location.href, location.assign, location.replace)

If a redirect to the canary destination is detected, the tool flags the URL as vulnerable and records clear evidence.

Why it’s safe
No redirect following: requests are issued with redirect handling disabled

Benign payloads only (https://example.com, //example.com, and encoded variants)

Timeouts & optional rate limiting to avoid stressing targets

No third-party services: everything runs locally in your browser

Key features
Test one or many URLs (paste multiple; one per line)

Auto-detect common redirect parameters (next, redirect_uri, returnTo, etc.) or specify your own

Choose GET or HEAD, set timeout and delay between requests

View results inline and Export JSON with full evidence (status, header, mechanism)

Clear legal/ethical banner; intended for authorized testing only

Typical use cases
Security reviews of login flows, OAuth/OIDC callbacks, and post-login redirect chains

AppSec CI/spot checks during release hardening

Bug bounty triage and validation

How it works (high level)
You paste URLs to scan

The tool sets candidate redirect parameters to benign URLs (and encoded variants)

It sends requests with redirect=manual and inspects response headers and HTML

Findings are displayed and can be exported as JSON

Notes
Only test systems you own or have permission to assess

You may need to whitelist targets in your testing scope and follow responsible disclosure practices
