Official description

OpenPanel before 3.0.0 contains a missing authorization vulnerability in the onboarding.project tRPC mutation that allows non-admin organization members to create projects and mint write-type ingestion credentials, bypassing the admin-only policy. 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.
