Technical details

The vulnerability is a TOCTOU race condition in the verifyOTP function where the OTP attempt counter is incremented using a stale in-memory value without atomic transactions or row-level locking. An unauthenticated attacker can fire concurrent requests to the auth__verify_otp endpoint to bypass the 10-attempt lockout, brute-force the OTP code, and authenticate as any customer whose email or phone is known. The publicly obtainable nonce from unauthenticated endpoints does not provide protection.
