CVE-2026-90500Network attack vector

Arbitrary file upload via unvalidated avatar input

Published Sep 13, 2026 · Updated Sep 13, 2026

Unrestricted file upload in lenve vhr 1.0-SNAPSHOT allows remote attackers to store arbitrary files through the avatar endpoint. The /hr/userface handler sends the attacker-controlled File argument to FastDFSUtils.upload without restricting the supplied file type. The route is network reachable; public evidence does not establish whether authentication is required or whether stored content can execute.
