An issue was discovered in clerk-js 5.88.0 allowing attackers to bypass the OAuth authentication flow by manipulating the request at the OTP verification stage. NOTE: this is disputed by the Supplier because there is no available information to reproduce the issue, and because an OAuth authentication flow issue would be fixed in a backend component, not within clerk-js itself (which is solely a frontend component).

Weakness

This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
