Deeper analysis
CVE-2026-28016 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 (LFI), in the ThemeREX Luxury Wine WordPress theme. This issue affects Luxury Wine versions from n/a through 1.1.14 and is associated with CWE-98. 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), indicating high severity due to network accessibility, high attack complexity, no privileges or user interaction required, and high impacts on confidentiality, integrity, and availability.
Remote attackers can exploit this vulnerability without authentication or user involvement, though it demands sophisticated techniques given the high complexity factor. Exploitation allows inclusion of arbitrary local files on the server, potentially leading to disclosure of sensitive data, arbitrary code execution if PHP files are targeted, or system compromise through chained attacks.
The Patchstack advisory documents this Local File Inclusion vulnerability in the WordPress Luxury Wine theme version 1.1.14 and provides vulnerability details for affected deployments.
