Vulnerability Details
The CVE-2026-28059 vulnerability is described as an improper control of filename for include/require statements in the PHP program, which allows for PHP local file inclusion. The affected product is the ThemeREX Dermatology Clinic theme, specifically from version n/a to <= 1.4.3. The CWE classification for this vulnerability is CWE-98, which pertains to improper control of the filename.
The CVSS version 3.1 vector for this vulnerability is CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, resulting in a base score of 8.1. This score indicates that exploitation of the vulnerability requires a high level of complexity, with no privileges required and no user interaction needed.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of filenames within the PHP application code. This could allow attackers to manipulate the input to include arbitrary files from the server, leading to the potential exposure of sensitive data.
The attack vector for this vulnerability is network-based, meaning it can be exploited remotely. The attack complexity is rated as high, suggesting that attackers would need to employ specific techniques to successfully exploit this vulnerability. No privileges are required to exploit this vulnerability, and user interaction is also not necessary.
The impacts of this vulnerability are significant, as successful exploitation could lead to high levels of confidentiality, integrity, and availability impact. Organizations should be aware of the potential for data breaches and unauthorized access to sensitive information.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2026-28059 is substantial. Organizations using the ThemeREX Dermatology Clinic theme should recognize the potential for exploitation and the subsequent impact on their operations. The blast radius of this vulnerability can extend beyond the immediate application, potentially affecting the overall security posture of the organization.
Given the CVSS score of 8.1 and the classification of high severity, organizations must assess their current patch management practices. The urgency for addressing this vulnerability is high, and organizations should prioritize patching immediately.
