File and directory exposure via configuration endpoint

Published Sep 3, 2023 · Updated Nov 21, 2024

Information disclosure in Dreamer CMS 4.1.0 through 4.1.3 allows attackers to access files or directories through a configuration endpoint. The public record identifies /upload/ueditorConfig?action=config but does not disclose the handler's exact missing check or which paths become accessible. Reachability is remote; published assessments disagree on required privileges, and no data modification or service interruption is established.
