What is CVE-2026-110468?

WidzialniCMS is exposed to an Unrestricted File Upload vulnerability through its /panel/controllers/save_photo.php endpoint. This security flaw arises from inadequate permission checks controlled by clients and insufficient validation of the currentpath parameter. An attacker, without requiring authentication, can exploit this vulnerability to upload arbitrary files to any location on the server, which may result in Remote Code Execution. The situation has been mitigated in version 2.5, which addresses the access control and validation issues.

Affected Version(s)
