CVE-2025-45777Public exploitNetwork attack vector

Unauthenticated account creation via trusted OTP response

Published Jul 25, 2025 · Updated Jul 25, 2025

Authentication bypass in Chavara Matrimony Site 2.0 allows remote attackers to create accounts without a valid email or mobile OTP. The registration flow trusts a client-visible OTP verification response, so changing HTTP 400 and success=false to HTTP 200 and success=true completes registration. No prior account or valid OTP is required; the demonstrated consequence is creation of fraudulent profiles tied to unverified contact details.
