A JWT issued for one organization can be replayed against another organization's API, allowing an attacker to read admin-only GraphQL fields like `participantDetails`, access participant personal data, and reach mutation paths they should not have access to.

The issue was discovered during a security audit by Radically Open Security. ## Full article daily.dev links to this article rather than hosting it.
