CVE-2025-4317Network attack vector

Code execution via unchecked remote logo upload

Published May 13, 2025 · Updated Apr 8, 2026

Unrestricted file upload in CodexThemes TheGem 5.10.3 and earlier allows remote authenticated users to execute PHP code through a logo URL. The thegem_get_logo_url() function downloads the configured logo URL and copies it into the public uploads directory using the URL extension without checking the file type or extension. Subscriber access is sufficient to obtain the theme-options nonce, set a remote PHP file as the logo, and trigger its execution for full site compromise.
