CVE-2026-2097Network attack vector

Authenticated code execution via unrestricted file upload

Published Feb 10, 2026 · Updated Feb 10, 2026

Unrestricted file upload in Flowring AgentFlow 0 allows remote authenticated users to execute arbitrary code on the server. The published advisory states that uploaded web shell backdoors execute on the server, but it does not disclose the affected endpoint or the precise file-validation or storage failure. Valid application credentials are required, and successful exploitation runs attacker-supplied code with the server process's privileges.
