Unauthenticated users can supply any file type, causing the server to store the file without restrictions. This allows attackers to upload potentially executable content, creating a path for remote code execution if the uploaded file can later be accessed and executed by the web server.

Although the vulnerability is not present in the CISA KEV catalog, its potential for remote code execution warrants attention. Exploitation requires an attacker to submit a form with a multiple file upload field that accepts a wildcard file type; no authentication or elevated permissions are needed. Once the malicious file is stored on the server, an attacker may execute it if the web server permits execution of the uploaded content."}}}}, "created": "2026-03-06T15:01:29.346541+00:00", "updated": "2026-04-15T20:00:06.626831+00:00", "vendors": ["glenwpcoder", "glenwpcoder$PRODUCT$drag_and_drop_multiple_file_upload_for_contact_form_7", "wordpress", "wordpress$PRODUCT$wordpress"]}
