CVE-2023-44312Network attack vector

Unauthenticated environment-variable disclosure via dump API

Published Jan 31, 2024 · Updated May 30, 2025

Information disclosure in Apache ServiceComb Service-Center 2.1.0 and earlier allows remote attackers to read server environment variables. The dump response model in pkg/model/dump.go includes process-environment data that the dump API serializes for callers. No credentials or user interaction are required, and the reported impact is limited to confidentiality.
