CVE-2024-6220Network attack vector

Unauthenticated arbitrary file upload via missing type validation

Published Jul 17, 2024 · Updated Apr 8, 2026

Arbitrary file upload in the Keydatas WordPress plugin 2.5.2 and earlier allows remote attackers to place files on the site server. The keydatas_downloadImages function accepts downloaded image content without validating the resulting file type before storing it. No credentials are required; code execution depends on the web server treating the uploaded file as executable content.
