CVE-2026-27202Public exploitNetwork attack vector

Unauthenticated file read via relative path traversal

Published Feb 20, 2026 · Updated Feb 20, 2026

Path traversal in GetSimple CMS Community Edition 3.3.22 and earlier allows remote attackers to read arbitrary server files. The Uploaded Files handler in upload.php constructs a pathname without neutralizing relative traversal elements; the advisory does not disclose the request parameter. No authentication or user interaction is required, and the disclosure can include confidential data stored on the host.
