Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly remediates the LFI vulnerability in the Stargaze WordPress theme by identifying, patching, and verifying fixes for the improper filename control in PHP include/require.

prevent

Prevents exploitation of the PHP Remote/Local File Inclusion by validating filenames and paths supplied to include/require statements against safe patterns or whitelists.

prevent

Mitigates LFI risks through secure configuration of PHP settings like open_basedir restrictions and disabling allow_url_include to limit arbitrary file access.

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?

LFI vulnerability in public-facing WordPress theme enables remote exploitation of public-facing application (T1190) and facilitates collection of data from arbitrary local PHP files on the system (T1005).

Deeper analysisAI

CVE-2026-28025 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, affecting the ThemeREX Stargaze WordPress theme. This flaw impacts all versions from n/a through 1.5 and is associated with CWE-98. Published on 2026-03-05, it 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 across confidentiality, integrity, and availability.

Unauthenticated remote attackers (PR:N) can exploit this vulnerability over the network (AV:N) without user interaction (UI:N), though it requires high attack complexity (AC:H) in an unchanged security scope (S:U). Successful exploitation allows attackers to achieve high-level impacts, including unauthorized access to local files via LFI, potentially leading to data disclosure, modification, or system disruption as reflected in the CVSS impact metrics.

The primary advisory from Patchstack details the Local File Inclusion vulnerability in the Stargaze WordPress theme version 1.5 and provides information on patches or mitigations, accessible at https://patchstack.com/database/Wordpress/Theme/stargaze/vulnerability/wordpress-stargaze-theme-1-5-local-file-inclusion-vulnerability?_s_id=cve.
