NewCVE-2026-67329 (opens in a new tab)How to fix?
Upgrade @better-auth/stripe to version 1.6.21, 1.7.0-beta.10 or higher.
Overview
@better-auth/stripe is a Stripe plugin for Better Auth
Affected versions of this package are vulnerable to Incorrect Authorization through the handling of organization subscription actions when the authorizeReference callback is used and both subscription.enabled and organization.enabled are set to true. An attacker can perform unauthorized billing actions on organizations they are a member of, such as canceling subscriptions, changing plans, restoring subscriptions, or accessing billing details, by manipulating the organization ID in the request query string to mismatch the active organization in their session. This is only exploitable if organization subscriptions are enabled, the authorizeReference callback is set, and users can join multiple organizations.
Workaround
This vulnerability can be mitigated by configuring the authorizeReference callback to approve only the caller's active organization and returning false when the requested ID does not match the active organization ID.
