Apache DevLake 1.0.3 Unauthenticated SSRF


Vendor: The Apache Software Foundation
Product web page: https://devlake.apache.org
Affected version: 1.0.3

Summary: Apache DevLake is an open-source dev data platform that ingests,
analyzes, and visualizes the fragmented data from DevOps tools to extract
insights for engineering excellence, developer experience, and community
growth. Apache DevLake is designed for developer teams looking to make
better sense of their development process and to bring a more data-driven
approach to their own practices. You can ask Apache DevLake many questions
regarding your development process. Just connect and query.

Desc: Apache DevLake exposes an unauthenticated data-source connection-test
endpoint whose request body supplies the target "endpoint" URL, which the
server then fetches with no authentication and no private-IP/metadata filtering
(the optional ENDPOINT_CIDR_BLACKLIST is disabled by default and only matches
literal IPs, so any hostname bypasses it). A remote attacker who can reach the
API can therefore coerce the server into issuing HTTP/HTTPS requests to arbitrary
internal hosts, read cloud-metadata and internal HTTP services, and port-scan
the internal network. By default the upstream response body is reflected back
in the error.

Tested on: Nginx/1.29
           MySQL/8.0.26
