Deeper analysis

CVE-2025-69400 is an Improper Control of Filename for Include/Require Statement vulnerability in PHP programs, specifically a PHP Remote File Inclusion issue that enables PHP Local File Inclusion (CWE-98). It affects the ThemeREX Yokoo WordPress theme, impacting all versions from n/a through 1.1.11. 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 its potential for significant impact.

Remote attackers can exploit this vulnerability over the network without requiring user privileges or interaction, though exploitation demands high attack complexity. Successful attacks allow attackers to include and potentially execute arbitrary local files on the server, leading to high confidentiality, integrity, and availability impacts, such as unauthorized access to sensitive data or system compromise.
