Attackers can repeatedly call the endpoint with a member session to obtain plaintext secrets, inject fake analytics events, poison business metrics, and consume the organization's usage budget.","summary":"OpenPanel before 3.0.0 lets any organization member call the onboarding.project tRPC mutation, which is meant to be admin-only.
