CVE-2026-2558Public exploitNetwork attack vector

Internal resource access via unvalidated download URL

Published Feb 16, 2026 · Updated Feb 16, 2026

SSRF in GeekAI Plus 4.2.0 through 4.2.4 allows remote authenticated users to read network-accessible resources via a crafted URL. The Download handler in api/handler/net_handler.go passes the unvalidated url query value directly to http.Get and copies successful response bodies to the caller. The published reproduction reports no authentication at /api/download, although the CNA assessment models low privileges; successful requests expose internal HTTP responses.
