CVE-2025-41396Network attack vector

Authenticated file overwrite via upload path traversal

Published Jul 31, 2025 · Updated Jul 31, 2025

Path traversal in PowerCMS 4.6, 5.3, and 6.7 and earlier allows remote authenticated users to overwrite arbitrary files through uploads. Public advisories identify the file-uploading feature but do not disclose the affected handler or how it fails to constrain attacker-controlled paths. Any product user who can upload a file can replace files writable by the web application, causing bounded integrity loss or a service interruption.
