{"id":"CVE-2026-93031","state":"PUBLISHED","title":"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","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.","publishedAt":"2026-09-18T19:36:29.297Z","updatedAt":"2026-09-19T14:11:38.229Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["WP Cloud Plugins/_deleeuw_ Use-your-Drive | Google Drive plugin for WordPress","_DeLeeuw_ Share-one-Drive | OneDrive & SharePoint plugin for WordPress","_DeLeeuw_ WP Cloud Plugins - Box (Lets-Box)","_DeLeeuw_ WP Cloud Plugins - Dropbox (Out-of-the-Box)"],"affected":[{"vendor":"WP Cloud Plugins/_deleeuw_","product":"Use-your-Drive | Google Drive plugin for WordPress","defaultStatus":"unaffected","versions":[{"version":"2.0","status":"affected","lessThanOrEqual":"3.8.3","versionType":"semver"}]},{"vendor":"_DeLeeuw_","product":"Share-one-Drive | OneDrive & SharePoint plugin for WordPress","defaultStatus":"unaffected","versions":[{"version":"2.0","status":"affected","lessThanOrEqual":"3.8.3","versionType":"semver"}]},{"vendor":"_DeLeeuw_","product":"WP Cloud Plugins - Box (Lets-Box)","defaultStatus":"unaffected","versions":[{"version":"2.0","status":"affected","lessThanOrEqual":"3.8.3","versionType":"semver"}]},{"vendor":"_DeLeeuw_","product":"WP Cloud Plugins - Dropbox (Out-of-the-Box)","defaultStatus":"unaffected","versions":[{"version":"2.0","status":"affected","lessThanOrEqual":"3.8.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a10ab4d6-318e-4dd6-9f81-ed25f181d074?source=cve","https://documentation.wpcloudplugins.com/other/changelog#id-3.9.0","https://wpcloudplugins.gitbook.io/docs/other/changelog"],"weaknesses":["CWE-434"],"ingestedAt":"2026-10-29T20:13:34.582Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/93xxx/CVE-2026-93031.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-93031","state":"PUBLISHED","datePublished":"2026-09-18T19:36:29.297Z","dateUpdated":"2026-09-19T14:11:38.229Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-17T15:11:46.407Z"},"containers":{"cna":{"title":"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","descriptions":[{"lang":"en","value":"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.
