CVE-2024-39676Network attack vector

Unauthenticated configuration disclosure via unrestricted Controller endpoint

Published Jul 24, 2024 · Updated Mar 14, 2025

Information disclosure in Apache Pinot before 1.0.0 allows remote attackers to read Controller system and configuration data. The Controller's /appconfigs handler returns architecture, operating-system, heap, ZooKeeper-path, and Pinot configuration values without enforcing access control. An unauthenticated network request to an exposed Controller is sufficient, and the reported impact is limited to reading those values.
