Deeper analysis

CVE-2026-22415 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, described as enabling PHP Local File Inclusion (despite the PHP Remote File Inclusion classification), in the WordPress theme The Mounty developed by AncoraThemes. This issue affects all versions of The Mounty from n/a through 1.1. It 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.

Unauthenticated remote attackers can exploit this vulnerability over the network, though it requires high attack complexity and no user interaction. Successful exploitation allows attackers to perform local file inclusion, potentially leading to high-level compromise of confidentiality by reading sensitive files, integrity violations through code execution or modification, and availability disruptions.

Mitigation details are available in advisories such as the Patchstack database entry at https://patchstack.com/database/Wordpress/Theme/the-mounty/vulnerability/wordpress-the-mounty-theme-1-1-local-file-inclusion-vulnerability?_s_id=cve. The vulnerability was published on 2026-03-05T06:16:15.310.
