CVE-2025-54381: BentoML server-side request forgery through file upload URL handling

Summary

BentoML versions 1.4.0 through 1.4.19 contain an SSRF vulnerability in the file upload processing system. Unauthenticated remote attackers can force the server to make arbitrary HTTP requests, because the multipart form data and JSON request handlers download files from user-provided URLs without checking whether they point to internal addresses, cloud metadata endpoints, or other restricted resources.

Mitigation

Fixed in 1.4.19 (version 1.4.19 contains a patch for the issue).
