CVE-2026-28058 is a high-severity vulnerability that allows for improper control of filename for include/require statements in PHP programs, specifically within the ThemeREX Dixon theme. This vulnerability allows PHP Local File Inclusion, which could potentially lead to unauthorized access to sensitive files on the server.
With a CVSS score of 8.1, this vulnerability poses significant risks to organizations using affected versions of the Dixon theme, specifically those from n/a through version 1.4.2.1. The vulnerability was published on March 5, 2026, and remains classified as deferred, indicating that it has not yet been fully addressed by the vendor.
Organizations utilizing this theme should prioritize patching immediately, as failure to do so leaves them vulnerable to potential exploitation by attackers.
The risk to organizations includes unauthorized access to server files, which could lead to further compromise or data leakage. As of now, there are no known exploits in the wild, but the nature of this vulnerability means that it could be leveraged by attackers in the future.
For organizations using the Dixon theme, immediate remediation steps should be taken to mitigate this risk.
Vulnerability Details
The vulnerability is categorized under CWE-98, which describes improper control of filename for include/require statements in PHP programs. This can allow an attacker to include files from the local filesystem, leading to unauthorized access or execution of malicious code.
The CVSS version 3.1 vector string for this vulnerability is: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. This indicates that the attack vector is network-based, with high complexity and no privileges required for exploitation, making it accessible to unauthenticated attackers.
The confidentiality, integrity, and availability impacts are all rated as high, meaning successful exploitation could lead to significant consequences for affected systems.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of input used in the filename for include or require statements. This flaw allows an attacker to manipulate the input to include arbitrary files from the server, effectively bypassing intended restrictions.
The attack vector is network-based, allowing potential attackers to exploit this vulnerability remotely. The attack complexity is rated as high, suggesting that successful exploitation may require specific conditions or knowledge about the target system.
No user interaction is required to exploit this vulnerability, further increasing the risk. The impacts on confidentiality, integrity, and availability are all rated as high, indicating that successful exploitation could lead to severe consequences.
Risk & Impact Analysis
Organizations using the Dixon theme are at risk of significant security incidents if they do not address this vulnerability promptly. The potential blast radius includes any server utilizing this theme, leading to unauthorized file access and potential data breaches.
Given the high CVSS score and the nature of the vulnerability, organizations should assess their exposure and prioritize patching as part of their remediation strategy. The longer this vulnerability remains unaddressed, the greater the potential for exploitation.
With the current exploitability rating being high, organizations should take this vulnerability seriously and apply the necessary patches or updates as soon as they become available.
