CVE-2026-28032 is a high-severity vulnerability affecting the ThemeREX Tuning plugin. This vulnerability allows improper control of filename for include/require statements in PHP programs, leading to a potential PHP Local File Inclusion (LFI) exploit. The issue affects versions of Tuning from n/a through 1.3. With a CVSS score of 8.1, this vulnerability presents a significant risk to organizations using affected versions of the plugin.
The high CVSS score indicates that the vulnerability can be exploited over a network with high complexity and does not require user interaction. Organizations should be especially concerned about the impacts on confidentiality, integrity, and availability, all rated as high. The exploitation of this vulnerability could lead to unauthorized access to sensitive files and potentially compromise the entire system.
Currently, there is no known public exploit for this vulnerability, and it is not listed in the KEV catalog. However, the potential impact is severe enough that organizations should prioritize patching immediately to mitigate risks associated with this flaw.
The vulnerability was published on March 5, 2026, and has been classified under CWE-98, which refers to the improper control of filenames in include statements. The urgency for defenders is clear, as this vulnerability could be leveraged to access sensitive data or execute arbitrary code.
Vulnerability Details
The vulnerability allows for PHP Local File Inclusion due to improper control of the filename in include/require statements. This issue specifically affects ThemeREX Tuning versions from n/a to 1.3. The CVSS score is 8.1, indicating a high severity level. The vulnerability's CWE classification is CWE-98.
Technical Analysis
The root cause of this vulnerability is the improper validation of filenames supplied to include/require statements within the PHP application. Attackers may exploit this vulnerability over the network, with a high attack complexity, meaning that they need to craft a specific input that is not easily achieved. No privileges are required, and the exploitation does not necessitate user interaction.
The impacts of successful exploitation could include unauthorized access to sensitive data, modification of files, and disruption of the service, resulting in high confidentiality, integrity, and availability impacts. Organizations should analyze their systems for this vulnerability and implement necessary security measures.
Risk & Impact Analysis
Risk to organizations includes potential data breaches, unauthorized access to sensitive files, and overall system compromise due to the high severity of the vulnerability. The blast radius for this vulnerability is significant, particularly for organizations relying on the ThemeREX Tuning plugin to manage critical functionalities.
With the CVSS score of 8.1, it is imperative for organizations to prioritize remediation in their patch cycles. The urgency is compounded by the potential for attackers to leverage this vulnerability in active campaigns, potentially impacting a wide range of systems and data.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects ThemeREX Tuning versions from n/a through 1.3. Organizations running these versions should take immediate action to ensure their systems are secure.
Mitigation & Remediation
Organizations should prioritize patching their ThemeREX Tuning installations to versions beyond 1.3. If an immediate patch is not available, organizations should implement network controls to restrict access to the affected systems. Additionally, monitoring for unusual file access patterns may help identify potential exploitation attempts.
For further security assessments, organizations may consider engaging in penetration testing to validate the effectiveness of their remediation efforts.
Detection Guidance
Organizations should watch for log indicators that may suggest unauthorized file access. Behavioral anomalies, such as unexpected changes to files or unauthorized access attempts, should be closely monitored. Network signatures may also help detect exploitation attempts.
