SCA: security update for better-auth (GHSA-cq3f-vc6p-68fh)

high Tenable Cloud Security Plugin ID 442635

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. From 1.6.0 until 1.6.11, the
 deviceAuthorization plugin treats any authenticated session as the owner of any pending device code
 because GET /device does not claim the row and POST /device/approve and POST /device/deny short-circuit
 when userId is unset, allowing an authenticated attacker who learns a valid user_code to bind the polling
 device to the attacker's account or deny the legitimate flow. This issue is fixed in version 1.6.11.
 (CVE-2026-45337)

Solution

Update the better-auth library and its related packages to version 1.6.11 or later.
