CVE-2026-4201Public exploitNetwork attack vector

Unauthenticated dangerous file upload via Upload

Published Mar 16, 2026 · Updated Mar 16, 2026

Unrestricted file upload in glowxq Glowxq-OJ 6f7c723090472057252040fd2bbbdaa1b5ed2393 allows remote attackers to store dangerous files. The Upload function in SysFileController.java accepts a remotely supplied file without a published type-validation or access-control boundary. No authentication is required; public evidence establishes file placement and limited confidentiality, integrity, and availability impact, but not code execution.
