| CVE-2026-67332 | 1 Better-auth | 2 Better-auth\/oauth-provider, Oauth-provider | 2026-08-01 | 6.4 Medium |
| @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-2026-53517 | 1 Better-auth | 2 Better Auth, Oauth-provider | 2026-07-15 | 8.1 High |
| Better Auth is an authentication and authorization library for TypeScript. From 1.4.8-beta.7 until 1.6.11, the @better-auth/oauth-provider POST /oauth2/token endpoint on the refresh_token grant performs a non-atomic read, validate, revoke, and mint sequence on the oauthRefreshToken row, allowing concurrent requests with the same parent refresh token to pass the revoked check and create forked refresh-token families; the vulnerable range also includes embedded better-auth plugin versions before 1.6.0. This issue is fixed in version 1.6.11. | ||||
| CVE-2026-41427 | 1 Better-auth | 3 Better-auth\/oauth-provider, Better Auth, Oauth-provider | 2026-05-13 | 6.5 Medium |
| 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. | ||||
