CVE-2026-11962
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe FileOrganizer WordPress plugin before version 1.2.0 fails to validate file types on multiple file-management operations beyond just the upload function. While CVE-2024-7985 added file-type validation to the upload operation, other file-management operations remain unprotected, allowing authenticated users with file-manager access to upload arbitrary PHP files and achieve remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the FileOrganizer plugin versionIn the WordPress admin dashboard, go to Plugins > Installed Plugins and find FileOrganizer. The version number is displayed below the plugin name. Alternatively, inspect the plugin main file header in wp-content/plugins/file-organizer/Affected if The installed version is lower than 1.2.0 (e.g., 1.1.x, 1.0.x, or any version before 1.2.0)
-
Confirm the plugin is activeIn Plugins > Installed Plugins, verify that FileOrganizer shows as Active. Inactive plugins do not expose the vulnerability.Affected if FileOrganizer is active and the version is below 1.2.0
-
Verify file-manager access is enabledCheck if the FileOrganizer file-manager functionality is accessible. This typically requires a user role with file-manager permissions (such as administrator or a custom role with file-manager access granted through the plugin settings).Affected if Authenticated users with file-manager role permissions can access file-management operations and the plugin version is below 1.2.0
-
Identify users with file-manager role permissionsReview user accounts and their assigned roles. FileOrganizer may create or modify roles to grant file-manager capabilities. Check Users > All Users and examine role assignments, or inspect the file-organizer roles/capabilities configuration.Affected if Any user account has a role that includes file-manager access and the plugin version is below 1.2.0
The environment is affected if FileOrganizer plugin version is below 1.2.0, the plugin is active, and any authenticated user has access to file-management operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate to FileOrganizer version 1.2.0 or later, which adds file-type validation to all file-management operations. Additionally, restrict file-manager access to only highly trusted users and consider disabling the premium add-on if sub-administrator role access extension is not needed.
FileOrganizer plugin version 1.2.0
- Update the FileOrganizer WordPress plugin to version 1.2.0 or later through the WordPress admin dashboard under Plugins > Installed Plugins
- Alternatively, update via WP-CLI: wp plugin update file-organizer
- Verify the update was successfully applied by checking the plugin version in the Plugins list
- Ensure file-type validation is functioning on all file-management operations after the update
- Review user permissions to ensure only trusted users have file-manager access
