Deeper analysis

CVE-2026-28060 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98 and labeled as PHP Remote File Inclusion, but enabling PHP Local File Inclusion in the ThemeREX S.King (stephanie-king) WordPress theme. This flaw affects all versions of S.King from n/a through 1.5.3.

Unauthenticated attackers can exploit this vulnerability remotely over the network (AV:N), requiring high attack complexity (AC:H) with no privileges (PR:N) or user interaction (UI:N) needed, and unchanged scope (S:U). Successful exploitation yields high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), with an overall CVSS v3.1 score of 8.1, potentially allowing inclusion and execution of arbitrary local files.

The Patchstack advisory (https://patchstack.com/database/Wordpress/Theme/stephanie-king/vulnerability/wordpress-s-king-theme-1-5-3-local-file-inclusion-vulnerability?_s_id=cve) documents the local file inclusion vulnerability in the WordPress S.King theme up to version 1.5.3, recommending mitigation through theme updates to patched releases.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
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.
Why these techniques?

Unauthenticated remote LFI vulnerability in public-facing WordPress theme directly enables exploitation of public-facing application (T1190) and facilitates reading data from local system files (T1005).

prevent

Directly mandates identification, reporting, and correction of flaws like the PHP LFI vulnerability in the S.King WordPress theme through timely patching to versions beyond 1.5.3.

prevent

Enforces validation of user-supplied filenames in PHP include/require statements to block path traversal and prevent arbitrary local file inclusion.

prevent

Requires secure PHP configuration settings, such as open_basedir restrictions, to limit file access scope and mitigate LFI exploitation impact.
