The concurrent authorization-code redemption test (added on main for GHSA-7w99-5wm4-3g79) exchanged the code against `/api/auth/oauth2/callback/test`, but next renamed that callback path to `/api/auth/callback/test`. The merge kept next's code-minting helper while preserving main's exchange path, so the race winner failed redirect_uri validation and no caller minted a token, tripping the "exactly one success" assertion. Because that test threw before closing its listener on port 3000, the leaked server poisoned the later EdDSA and HS256 oidc-jwt tests (stale server, code not found on consume). Aligning the exchange path to next fixes all three.
Better Auth
Better Auth is a framework-agnostic authentication (and authorization) framework for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code in a short amount of time. Whether you need 2FA, multi-tenant support, or other complex features, it lets you focus on building your actual application instead of reinventing the wheel.
Why Better Auth
Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often require a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
