Deeper analysis

CVE-2026-27075 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as a PHP Remote File Inclusion issue that enables PHP Local File Inclusion. It affects the Belfort WordPress theme developed by Mikado-Themes, impacting all versions from n/a through 1.0 inclusive. The vulnerability is associated with CWE-98 and 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 and significant impacts on confidentiality, integrity, and availability.

An unauthenticated remote attacker can exploit this vulnerability over the network, though it requires high attack complexity and no user interaction. Exploitation allows the attacker to perform local file inclusion, potentially leading to unauthorized access to sensitive files, code execution, or other high-impact compromises on the affected WordPress site.
