Deeper analysis

CVE-2026-28006 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as PHP Remote File Inclusion but enabling PHP Local File Inclusion, in the ThemeREX Yungen WordPress theme. This issue affects Yungen versions from n/a through 1.0.12. The vulnerability carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-98.

Unauthenticated attackers can exploit this vulnerability remotely over the network, requiring high attack complexity but no privileges or user interaction. Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability, potentially enabling local file inclusion to access sensitive files, execute arbitrary code, or disrupt services on affected WordPress installations running the vulnerable theme.

The Patchstack advisory (https://patchstack.com/database/Wordpress/Theme/yungen/vulnerability/wordpress-yungen-theme-1-0-12-local-file-inclusion-vulnerability?_s_id=cve) documents the local file inclusion vulnerability in Yungen theme version 1.0.12 and provides details relevant to mitigation strategies for WordPress environments.
