CVE:CVE-2026-67332 vulnerable 2026-09-16 04:33:05.680502 @better-auth/oauth-provider before 1.7.0-beta.4 Authorization Bypass
MEDIUM (6.4)
@better-auth/oauth-provider before 1.7.0-beta.4 fails to bind access-token audience to the authorization grant, allowing clients to request tokens for unrelated resources. Attackers can complete an OAuth flow and obtain access tokens whose audience targets resource servers the authorization never covered, bypassing intended authorization boundaries.

CVE:CVE-2026-41427 vulnerable 2026-06-08 08:03:15.373104 Better Auth OAuth 2.1 Provider: Unprivileged users can register OAuth clients
Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.5, the clientPrivileges option documents a create action, but the OAuth client creation endpoints did not invoke the hook before persisting new clients. Deployments that configured clientPrivileges to restrict client registration were not actually restricted — any authenticated user could reach the create endpoints and register an OAuth client with attacker-chosen redirect URIs and metadata. This vulnerability is fixed in 1.6.5.
