Deeper analysis

CVE-2026-22379 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as PHP Remote File Inclusion but manifesting as PHP Local File Inclusion (LFI), affecting the Netmix WordPress theme by AncoraThemes. The issue impacts Netmix versions from n/a through 1.0.10, stemming from inadequate validation of filenames used in PHP include or require statements.

Unauthenticated remote attackers can exploit this vulnerability over the network without user interaction, though it demands high attack complexity (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, base score 8.1). Exploitation enables high-impact compromise of confidentiality, integrity, and availability, allowing inclusion of arbitrary local files on the server (CWE-98).

The Patchstack advisory provides details on this Local File Inclusion vulnerability in the Netmix WordPress theme version 1.0.10; security practitioners should consult https://patchstack.com/database/Wordpress/Theme/netmix/vulnerability/wordpress-netmix-theme-1-0-10-local-file-inclusion-vulnerability?_s_id=cve for mitigation guidance and patches.
