CVE-2025-27888Public exploitNetwork attack vector

Authenticated SSRF via crafted management proxy URL

Published Mar 20, 2025 · Updated Mar 25, 2025

Server-side request forgery in Apache Druid before 31.0.2 and version 32.0.0 allows remote authenticated users to redirect proxy requests. The management proxy treats a specially crafted URL as an arbitrary upstream server destination instead of constraining it to a Druid service. The proxy is enabled in the out-of-box configuration; exploitation requires authentication and can expose users to cross-site scripting or request forgery.
