{"id":"CVE-2026-93031","published":"2026-09-18T20:17:31.630","lastModified":"2026-09-21T13:33:33.387","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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-434"],"vendors":[],"products":[],"references":[{"url":"https://documentation.wpcloudplugins.com/other/changelog#id-3.9.0","tags":[]},{"url":"https://wpcloudplugins.gitbook.io/docs/other/changelog","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a10ab4d6-318e-4dd6-9f81-ed25f181d074?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw allows attackers to upload arbitrary files, leading to potential remote code execution, due to missing capability checks and lack of file validation.","exploitability":"Exploitation is moderately hard as it requires authenticated access with subscriber-level permissions and knowledge of the import process.","blast_radius":"If exploited, the impact could be severe, as it allows remote code execution, potentially compromising the entire WordPress site.","remediation":"Disable the affected plugins or upgrade to version 3.8.4 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","web","upload","auth-bypass"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-29T09:21:09.695Z"}}
