Redirect URI manipulation is the abuse of redirect destination handling in OAuth or OIDC flows to capture codes, tokens, or user trust. It matters because redirect handling is a critical trust boundary in modern authentication flows.
What is Redirect URI Manipulation?
If allowed redirect URIs are too broad, loosely matched, or chainable through other endpoints, attackers may receive sensitive authorization artifacts or trick users into unsafe paths. Exact registration and careful validation are key defenses.
What Redirect URI Manipulation Commonly Supports
Common uses include OAuth security review, app registration hardening, SSO flow testing, and identity provider governance.
Redirect URI Manipulation vs. Strict Redirect Destination Validation
Redirect URI manipulation exploits loose redirect controls. Strict validation permits only precisely intended callback destinations.
Frequently Asked Questions
Why are redirect URIs sensitive?
Because authorization codes and tokens often pass through them during login and consent flows.
Does HTTPS alone solve redirect risk?
No. The destination itself still has to be tightly controlled and verified.
