Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

A server-side request forgery vulnerability in HumanSignal Label Studio through 1.24.0.dev0 exists because SSRF_PROTECTION_ENABLED is set to false by default. The import-from-URL endpoint fetches any caller-supplied URL including internal loopback addresses on the default installation. An authenticated user can use this to reach internal services, cloud metadata endpoints, and other resources not intended for external access.
