SCA: security update for @better-auth/oauth-provider (GHSA-xr8f-h2gw-9xh6)

high Tenable Cloud Security Plugin ID 440910

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-41427)

Solution

Update the @better-auth/oauth-provider library and its related packages to version 1.6.5 or later.
