CVE-2025-26892Public exploitNetwork attack vector

Authenticated code execution via unchecked theme upload

Published May 19, 2025 · Updated Apr 28, 2026

Unrestricted file upload in dkszone Celestial Aura 2.2 and earlier allows remote authenticated users to execute PHP code via theme settings. The CA-settings handler accepts CA_hdrimage uploads into the web-accessible WordPress uploads directory without nonce, file-type, or extension validation. Subscriber-level access is sufficient to place and invoke a PHP web shell, enabling code execution with the web server's privileges.
