CVE-2023-44313Network attack vector

Sensitive data disclosure via unrestricted schema requests

Published Jan 31, 2024 · Updated Feb 13, 2025

SSRF in Apache ServiceComb Service-Center 2.1.0 and earlier allows remote attackers to read sensitive server data via frontend requests. The frontend /testSchema/* handler builds an HTTP URL from the X-InstanceIP header and request path without restricting the destination. Apache's assessment requires user interaction, although the advisory does not describe that interaction; successful requests expose data reachable from the server.
