CVE-2026-63044Network attack vector

Authenticated SSRF via testConnection endpoint

Published Aug 20, 2026 · Updated Aug 20, 2026

Server-side request forgery in Apache InLong 2.0.0 before 2.4.0 allows remote authenticated users to reach internal hosts via /api/node/testConnection. The InLong Manager testConnection endpoint accepted user-supplied node connection parameters for outbound HTTP or TCP connectivity checks, and the linked Apache fix work states that the endpoint lacked role enforcement and SSRF target validation for loopback, link-local, and RFC1918 destinations. Any account that can authenticate to Manager, even without an admin role, can use the server as a network pivot for internal service probing or interaction, with no published evidence of code execution or data modification.
