CVE-2026-72560Network attack vector

Authenticated internal-service access via default-disabled SSRF filtering

Published Aug 11, 2026 · Updated Aug 11, 2026

Server-side request forgery in HumanSignal Label Studio through 1.24.0.dev0 allows remote authenticated users to access internal services. The import-from-URL path passes caller-supplied URLs to the server-side fetch routine while SSRF_PROTECTION_ENABLED defaults to false. Any authenticated user who can import from a URL can make the server contact loopback, cloud metadata, or other network resources that are inaccessible to the user directly.
