CVE-2025-14836Public exploitNetwork attack vector

Sensitive-data exposure via undisclosed cleartext file write

Published Dec 17, 2025 · Updated Dec 17, 2025

Cleartext storage in ZZCMS 2025 User Data Storage Module allows remote authenticated users to expose sensitive data through user_save.php. The public record identifies /reg/user_save.php as the storage locus but does not disclose which user field is written or the unencrypted write operation. Exploitation requires high privileges and no user interaction; the bounded consequence is disclosure of data saved in cleartext, without integrity or availability impact.
