What is CVE-2026-11962?
CVE-2026-11962 is a high-severity vulnerability in Unknown FileOrganizer, published on 6 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
