## Affected

- marqo-ai marqo: through 2.26.0

## Description

Marqo 2.26.0 contains a server-side request forgery vulnerability in the add_documents endpoint that allows unauthenticated attackers to trigger requests to arbitrary URLs by supplying malicious media field values. Attackers can exploit download_image_from_url and fetch_content_sample functions which lack destination filtering and host validation to access internal services and cloud metadata endpoints.
