The vulnerability CVE-2026-22494 affects the ThemeREX Good Homes theme for WordPress, specifically versions up to 1.3.13. It arises from improper validation or control of filenames used in PHP include or require statements, enabling PHP Local File Inclusion. This can allow an attacker to include arbitrary local files on the server, potentially exposing sensitive information or enabling further code execution. The CVSS v3.1 base score is 8.1, indicating high severity with network attack vector, high complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or vendor advisory is currently provided, and the product is not a cloud service.

Successful exploitation of this vulnerability could lead to disclosure of sensitive files on the server, unauthorized code execution, and full compromise of the affected system's confidentiality, integrity, and availability. Given the high CVSS score (8.1), the impact is considered severe. However, no known exploits have been reported in the wild so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or removing the affected theme or applying manual code review and hardening to prevent local file inclusion. Monitor official ThemeREX channels for updates or patches addressing this vulnerability.
