CVE-2024-13091Network attack vector

Unauthenticated arbitrary file upload via missing validation

Published Jan 21, 2025 · Updated Apr 8, 2026

Arbitrary file upload in QuantumCloud WPBot Pro 13.5.4 and earlier allows remote attackers to place files on a WordPress server. The qcld_wpcfb_file_upload function accepts untrusted files without validating their types before storing them. The unauthenticated route requires both ChatBot Conversational Forms and Conversational Form Builder Pro; server-executable uploads enable code execution.
