{"cve":"CVE-2026-5364","nvd":{"published":"2026-04-24T06:16:08.480","modified":"2026-06-17T10:58:54.403","status":"Deferred","description":"The Drag and Drop File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file upload in versions up to, and including, 1.1.3. This is due to the plugin extracting the file extension before sanitization occurs and allowing the file type parameter to be controlled by the attacker rather than being restricted to administrator-configured values, which when combined with the fact that validation occurs on the unsanitized extension while the file is saved with a sanitized extension, allows special characters like '$' to be stripped during the save process. This makes it possible for unauthenticated attackers to upload arbitrary PHP files and potentially achieve remote code execution, however, an .htaccess file and name randomization is in place which restricts real-world exploitability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-434"],"references":["https://plugins.trac.wordpress.org/browser/drag-and-drop-file-upload-for-contact-form-7/tags/1.1.2/backend/index.php#L147","https://plugins.trac.wordpress.org/browser/drag-and-drop-file-upload-for-contact-form-7/tags/1.1.2/backend/index.php#L158","https://plugins.trac.wordpress.org/browser/drag-and-drop-file-upload-for-contact-form-7/tags/1.1.2/backend/index.php#L181","https://plugins.trac.wordpress.org/browser/drag-and-drop-file-upload-for-contact-form-7/tags/1.1.2/frontend/index.php#L15","https://plugins.trac.wordpress.org/browser/drag-and-drop-file-upload-for-contact-form-7/trunk/backend/index.php#L147"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-5364","score":0.0106,"percentile":0.64573,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
