Executive Summary

CVE-2025-68543 is a Local File Inclusion (LFI) vulnerability in the WordPress Diza Theme versions up to and including 1.3.15. It allows an unauthenticated attacker to include and display local files from the target website. This happens due to improper control of the filename used in include/require statements in the PHP program.

Because of this, sensitive information such as database credentials can be exposed. The vulnerability is classified under the OWASP Top 10 category A3: Injection and has a high severity CVSS score of 8.1.

Mitigation Strategies

The most immediate and effective mitigation step is to update the WordPress Diza Theme to version 1.3.16 or later, where the vulnerability has been patched.

Until the update can be applied, it is strongly advised to implement mitigation rules to block attacks targeting this vulnerability. Patchstack provides such mitigation rules to protect sites from exploitation.

Additional steps include:

• Deploy a web application firewall (WAF) with rules to detect and block Local File Inclusion attempts.
• Monitor web server logs for suspicious requests attempting file inclusion.
• Restrict file permissions and access to sensitive files on the server to minimize impact.
