CVE-2024-56736Network attack vector

Authenticated data disclosure via OSS configuration SSRF

Published Apr 16, 2025 · Updated Apr 16, 2025

Server-side request forgery in Apache HertzBeat before 1.7.0 allows remote authenticated users to read network-accessible data via OSS configuration. The OSS configuration API causes the server to contact an attacker-selected destination, but Apache has not disclosed the affected handler or missing validation. A valid HertzBeat account is required, and the published impact is limited to confidentiality rather than data modification or service interruption.
