Technical details
An unrestricted file upload vulnerability (CWE-434) exists in the Kids Gift Shop theme for WordPress in versions up to and including 0.5.4. The flaw allows an authenticated attacker with Subscriber-level permissions to upload files with dangerous extensions, such as .php, to the web server. Because the application fails to properly validate the file type or content, an attacker can achieve remote code execution (RCE) and full site compromise. The vulnerability has been addressed in version 0.5.5.
