CVE-2026-3052Public exploitNetwork attack vector

Authenticated internal resource access via arbitrary proxy URLs

Published Feb 24, 2026 · Updated Feb 24, 2026

Server-side request forgery in DataLinkDC Dinky 1.2.0 through 1.2.5 allows remote authenticated users to read internal HTTP resources. FlinkProxyController.proxyUba removes the /api/flink/ prefix, treats the remaining attacker-controlled absolute URL as a request target, executes it, and returns the response. Any valid session can reach the proxy, exposing resources accessible from the Dinky server without directly granting data modification or service interruption.
