# HUNT-OPEN-REDIRECT — Open Redirect

## Crown Jewel Targets

Open redirect alone is Low. Chained to OAuth = Critical (ATO).

**Highest-value chains:**
- **Open redirect → OAuth auth code theft** — redirect_uri contains open redirect on trusted domain → auth code sent to attacker → ATO
- **Open redirect → phishing** — users trust the URL because it starts with target.com
- **Open redirect → SSRF escalation** — if redirect followed server-side → SSRF
- **Open redirect → session fixation** — force user to login endpoint with pre-set session
