Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match
prevent

Remediating the specific PHP Local File Inclusion flaw in the Dermatology Clinic WordPress theme prevents unauthenticated attackers from including arbitrary local files.

SI-10 Information Input Validation good match
prevent

Validating filenames used in PHP include/require statements directly mitigates CWE-98 by ensuring only authorized, safe paths are processed.

CM-6 Configuration Settings good match
prevent

Enforcing secure PHP configuration settings, such as open_basedir restrictions, limits the scope of local file access even if improper includes occur.

Security SummaryAI

CVE-2026-28059 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98, that enables PHP Local File Inclusion in the ThemeREX Dermatology Clinic WordPress theme. This issue affects all versions of the theme from n/a through 1.4.3. 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 its potential for significant impact despite elevated complexity.

Unauthenticated attackers (PR:N) can exploit this over the network (AV:N) without user interaction (UI:N), though it requires high attack complexity (AC:H). Successful exploitation allows arbitrary local file inclusion, leading to high confidentiality (C:H), integrity (I:H), and availability (A:H) impacts, such as reading sensitive files or potentially executing code if exploitable files are accessible on the server.

Patchstack advisories provide details on the vulnerability in the Dermatology Clinic theme version 1.4.3, including mitigation guidance available at https://patchstack.com/database/Wordpress/Theme/dermatology-clinic/vulnerability/wordpress-dermatology-clinic-theme-1-4-3-local-file-inclusion-vulnerability?_s_id=cve.

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.
attack.mitre.org →
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.
attack.mitre.org →
T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
attack.mitre.org →
Why these techniques?

LFI vulnerability in public-facing WordPress theme directly enables T1190 (exploit public-facing application), facilitates T1005 (data from local system via arbitrary file read), and T1552.001 (credentials in files like wp-config.php).
