Vulnerability in Fileorganizer

CVE-2026-11962

The FileOrganizer WordPress plugin before 1.2.0 does not validate the file type on several of its file-management operations, allowing authenticated users who have been granted file-manager access — which its premium add-on can extend to sub-administrator roles — to upload arbitrary PHP files and achieve remote code execution. This is an incomplete fix of CVE-2024-7985, which only added file-type validation to the upload operation.
