Deeper analysis

CVE-2026-39681 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98 and described as enabling PHP Local File Inclusion despite being labeled as PHP Remote File Inclusion. It affects the ApusTheme Homeo WordPress theme, impacting all versions from n/a through 1.2.59.

The vulnerability has a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating exploitation is possible over the network by low-privileged users (PR:L) with high attack complexity and no user interaction. Successful attacks can result in high impacts to confidentiality, integrity, and availability, potentially allowing arbitrary file inclusion leading to sensitive data exposure, code execution, or system compromise on affected WordPress sites running the vulnerable theme.

Patchstack has published an advisory detailing the local file inclusion vulnerability in Homeo theme version 1.2.59, available at https://patchstack.com/database/Wordpress/Theme/homeo/vulnerability/wordpress-homeo-theme-1-2-59-local-file-inclusion-vulnerability?_s_id=cve, which security practitioners should consult for mitigation guidance and patch information.

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

T1505.003 Web Shell Persistence

Adversaries may backdoor web servers with web shells to establish persistent access to systems.

Why these techniques?

LFI in public-facing WordPress theme directly enables T1190 exploitation of public-facing apps; facilitates T1005 by allowing arbitrary local file reads for data exposure; and T1505.003 via file inclusion for web shell-based code execution and compromise.
