CVE-2024-35324Known exploitationNetwork attack vector

Unauthenticated arbitrary file upload via preview.php

Published May 28, 2024 · Updated Feb 13, 2025

Arbitrary file upload in Douchat 4.0.5 allows remote attackers to write attacker-supplied files through preview.php. The available CNA record identifies Public/Plugins/webuploader/server/preview.php as the affected locus but does not disclose the failed validation or file-write operation. No authentication or user interaction is required; successful exploitation writes attacker-controlled content to the server, while code execution is not established by the published record.
