CVE-2026-28120 is classified as a high-severity vulnerability due to its CVSS score of 8.1. This vulnerability allows improper control of filename for include/require statements in PHP applications, specifically affecting the ThemeREX Dr.Patterson theme, which permits local file inclusion. The risk to organizations includes unauthorized access to sensitive files, which can lead to further system compromises.
The vulnerability was published on March 5, 2026, and affects all versions of Dr.Patterson up to and including 1.3.2. Given the potential for exploitation, organizations using this theme should address the vulnerability urgently to mitigate risks associated with local file inclusion.
Currently, there is no public exploit confirmed for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the high CVSS score indicates that organizations must remain vigilant and adopt proactive security measures.
Organizations should prioritize patching immediately. Delaying remediation could expose them to significant risks, including data breaches and unauthorized access to their systems.
Vulnerability Details
The vulnerability arises from improper control in the handling of PHP include/require statements, which can be exploited to include local files. This vulnerability falls under the Common Weakness Enumeration (CWE) classification CWE-98. The attack vector for this vulnerability is categorized as network-based, with a high attack complexity, requiring no privileges and no user interaction. The impacts of this vulnerability encompass high confidentiality, integrity, and availability risks.
Technical Analysis
The root cause of CVE-2026-28120 stems from a failure to properly sanitize user inputs related to file paths, allowing attackers to manipulate file inclusion mechanisms within the application. The attack complexity is high, requiring an understanding of the underlying PHP application structure. Privileges required are none, and user interaction is also not needed, making this vulnerability particularly dangerous.
Risk & Impact Analysis
The potential real-world deployment risk associated with this vulnerability includes the possibility of attackers gaining access to sensitive application files, which can lead to further attacks on the system or data leakage. Organizations using affected versions of the Dr.Patterson theme should assess their exposure and take immediate action to mitigate this risk. The urgency to address this vulnerability is heightened by its high CVSS score and the potential impact on organizational operations.
