Deeper analysis

CVE-2026-28013 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, known as PHP Remote File Inclusion, that enables PHP Local File Inclusion in the ThemeREX Kratz WordPress theme. This issue affects Kratz versions from n/a through 1.0.12 and is associated with CWE-98. The vulnerability was published on 2026-03-05 with 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).

Unauthenticated remote attackers can exploit this vulnerability over the network, though it requires high attack complexity and no user interaction. Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability, potentially enabling local file inclusion to read sensitive files or, in some cases, lead to further code execution depending on the included files.

The Patchstack advisory provides details on this Local File Inclusion vulnerability in the Kratz WordPress theme version 1.0.12, including mitigation guidance, available at https://patchstack.com/database/Wordpress/Theme/kratz/vulnerability/wordpress-kratz-theme-1-0-12-local-file-inclusion-vulnerability?_s_id=cve.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates improper filename control in PHP include/require by requiring validation of user-supplied inputs to prevent local file inclusion of arbitrary files.

SI-2 Flaw Remediation good match
prevent

Requires timely discovery, assessment, and patching of the specific LFI flaw in Kratz WordPress theme versions through 1.0.12.

CM-6 Configuration Settings good match
prevent

Enforces secure PHP configuration settings such as open_basedir restrictions to limit filesystem access and block LFI exploitation.
