# CVE-2026-93031: WP Cloud Plugins Use-your-Drive, Out-of-the-Box, Share-one-Drive, and Lets-Box \<= 3.8.3 - Authenticated (Subscriber+) Arbitrary File Upload via Media Import

- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-09-18 · Updated: 2026-09-19

## Affected

- WP Cloud Plugins/\_deleeuw\_ Use-your-Drive | Google Drive plugin for WordPress: from 2.0, through 3.8.3
- \_DeLeeuw\_ Share-one-Drive | OneDrive & SharePoint plugin for WordPress: from 2.0, through 3.8.3
- \_DeLeeuw\_ WP Cloud Plugins - Box (Lets-Box): from 2.0, through 3.8.3
- \_DeLeeuw\_ WP Cloud Plugins - Dropbox (Out-of-the-Box): from 2.0, through 3.8.3

## Description

The WP Cloud Plugins Use-your-Drive, Out-of-the-Box, Share-one-Drive, and Lets-Box plugins for WordPress are vulnerable to Arbitrary File Upload in all versions from 2.0 up to, and including, 3.8.3 via the download_file_to_uploads function. This is due to the import action being registered for unauthenticated users via wp_ajax_nopriv_, a missing capability check in can_import(), and the imported file's extension and contents not being validated against get_allowed_mime_types() before it is written to the uploads directory. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible.

## What to do
