Deeper analysis

CVE-2025-54690 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, known as PHP Remote File Inclusion, that enables PHP Local File Inclusion in the themeStek Xinterio WordPress theme. This issue affects Xinterio versions from n/a through 4.2 and is associated with CWE-98.

The vulnerability has 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 exploitation is possible over the network by unauthenticated attackers (PR:N) with no user interaction required (UI:N), though it demands high attack complexity (AC:H). Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability (C:H/I:H/A:H) within unchanged scope (S:U), potentially enabling attackers to read local files or execute arbitrary code depending on server configuration.
