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.
AnalysisAI
Server-side request forgery in Marqo ≤ 2.26.0 allows unauthenticated remote attackers to force the server to issue HTTP requests to arbitrary internal or external URLs by supplying attacker-controlled values in media fields of the add_documents API endpoint. The vulnerability originates in the inference orchestrator's image download component - specifically the download_image_from_url and fetch_content_sample functions in image_download.py - which perform no host validation or destination filtering before fetching user-supplied URLs. …
