CVE-2024-40544Public exploitNetwork attack vector

Internal resource access via maintenance task SSRF

Published Jul 12, 2024 · Updated Mar 26, 2025

Server-side request forgery in PublicCMS 4.0.202302.e allows remote authenticated users to access internal resources through a maintenance task. The public record identifies the administrative maintenance system-task editor as the affected locus but does not disclose the request parameter or server-side fetch operation. A low-privileged authenticated session is required; successful exploitation makes requests from the server's network position, while response-return behavior is undocumented.
