Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

BentoML versions 1.4.0 before 1.4.19 (PyPI package bentoml) contain a server-side request forgery flaw in file upload handling, where URLs supplied in multipart form fields or JSON bodies are downloaded by the server without checking for internal network addresses. An unauthenticated remote attacker who can reach an endpoint with file-type parameters can make the server send arbitrary HTTP requests, which may expose internal services or cloud metadata. The fix is to upgrade to bentoml 1.4.19.
