Analysis

AI-generated

Technical impact

This vulnerability allows a subscriber to upload an arbitrary file through the Kids Gift Shop WordPress theme’s upload interface. The flaw enables an attacker to place malicious files on the server, potentially leading to full remote code execution and compromising the affected website’s confidentiality, integrity, and availability. The associated weakness is identified as CWE-434, reflecting a lack of proper file type validation.

Affected Systems

The issue affects all installations of the Kids Gift Shop theme from themagnifico52 with version 0.5.4 or earlier. The only known fixed release is version 0.5.5, which removes the insecure upload capability.

Risk and Exploitability

With a CVSS score of 9.9, the risk is considered very high. The EPSS score is not available, but the lack of CISA KEV listing does not diminish the urgency, as the flaw permits unauthenticated or minimal-privilege attackers to exploit the uploading mechanism. The attack likely proceeds via the web interface and can be triggered by any user with subscriber-level permissions.

Remediation

Vendor Solution

Update the WordPress Kids Gift Shop Theme to the latest available version (at least 0.5.5).


OpenCVE Recommended Actions

  • Apply the latest patch by updating the Kids Gift Shop Theme to at least version 0.5.5
  • If an update cannot be performed immediately, disable or remove the upload feature from the child theme or use a security plugin to restrict upload types to a whitelist
  • Implement server‑side validation or file scanning to ensure only expected file formats are accepted and monitor upload logs for suspicious activity
