Deeper analysis

CVE-2026-28051 is an Improper Control of Filename for Include/Require Statement vulnerability in PHP programs, classified as a PHP Remote File Inclusion issue that enables PHP Local File Inclusion (CWE-98), affecting the ThemeREX Yacht Rental (yacht-rental) WordPress theme. The vulnerability impacts all versions from n/a through 2.6 inclusive. Published on 2026-03-05, it carries a CVSS v3.1 base score of 8.1 (High: AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).

Remote unauthenticated attackers (PR:N) can exploit this over the network (AV:N) without user interaction (UI:N), though it requires high attack complexity (AC:H). Successful exploitation enables high-impact outcomes on confidentiality, integrity, and availability (C:H/I:H/A:H), such as including and executing arbitrary local files, potentially leading to sensitive data exposure, code execution, or service disruption on the targeted WordPress site.
