Open Redirect Checker
Probe common redirect parameters for unvalidated external destinations using safe example.com payloads.
Best for teams hardening login, logout, marketing campaign links, and OAuth callback flows that accept return, next, or redirect parameters.
What This Tool Checks
- Parameter abuse probing
- HTML link/form discovery
- Bounded safe-active GET checks
Why It Matters
Open redirects let attackers craft trustworthy-looking links on your domain that send victims to malicious sites, weakening phishing defenses and OAuth return-path trust.
Best For
Best for teams hardening login, logout, marketing campaign links, and OAuth callback flows that accept return, next, or redirect parameters.
What To Do Next
Use confirmed probes to patch allowlist validation, then retest auth and logout URLs after deploying redirect guards.

What does the Open Redirect Checker look for?
Open Redirect Checker focuses on parameter abuse probing, html link/form discovery, bounded safe-active get checks. It is designed to help teams identify this category of weakness quickly and then move into broader workflows if deeper follow-up is needed.
What is the difference between Quick and Comprehensive mode?
Quick mode stays public for focused diagnostics. Comprehensive mode is intended for authenticated workflows where users need saved history, richer follow-up, and broader account-linked execution.
When should I use the full Vulnify platform instead?
Use the full platform when you need more than one focused diagnostic, want to keep reports and history, or need scheduled scans, exports, and broader vulnerability coverage beyond open redirect checker.
