Open redirect via unvalidated OAuth next parameter
Published Apr 27, 2026 · Updated Apr 27, 2026
Open redirect in hunvreus DevPush 0.3.2 allows remote attackers to send authenticated users to malicious sites through a crafted URL. The /api/google/authorize handler stores the unvalidated next parameter in the session, and the OAuth callback passes that value directly to RedirectResponse. Exploitation requires an authenticated user to follow the crafted link; the bounded result is browser redirection that can support phishing.
