CVE-2026-28069: High Vulnerability in ThemeREX Le Truffe

This vulnerability allows improper control of the filename for Include/Require statements within PHP programs, specifically affecting ThemeREX Le Truffe versions up to 1.1.7. The CVSS score of 8.1 categorizes this as a high-severity vulnerability, emphasizing the serious nature of the risk.

Risk to organizations includes potential unauthorized access to sensitive information and manipulation of the application's integrity due to the Local File Inclusion (LFI) vulnerability. As attackers may leverage this weakness to execute arbitrary code, the urgency for defenders is critical.

Currently, there is no known public exploit for this vulnerability, and it has not been classified as actively exploited in the wild. However, the potential for exploitation remains a concern, and organizations should remain vigilant.

Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.

Vulnerability Details

The vulnerability is classified as a Local File Inclusion (LFI) vulnerability, which allows attackers to include files on a server through the web browser. The CVSS score is 8.1, indicating a high severity level, with implications for confidentiality, integrity, and availability.

The affected product is ThemeREX Le Truffe, with the vulnerability affecting all versions prior to 1.1.7. The issue was disclosed on March 5, 2026.

According to the Common Weakness Enumeration (CWE), this vulnerability is categorized as CWE-98, which pertains to improper control of filename for include/require statement.

Technical Analysis

The root cause of this vulnerability lies in the improper validation of filenames provided to Include/Require statements in PHP. This oversight allows attackers to manipulate the input, potentially leading to sensitive files being included and executed.

The attack vector for this vulnerability is network-based, allowing remote attackers to exploit the flaw without needing physical access to the system. The attack complexity is classified as high, requiring knowledge of the application’s structure and behavior.

No privileges are required for exploitation, and user interaction is not necessary, making this vulnerability particularly dangerous. The impacts on confidentiality, integrity, and availability are all rated as high, indicating severe consequences if successfully exploited.

Risk & Impact Analysis

Real-world deployment risk for organizations utilizing ThemeREX Le Truffe is significant due to the inherent vulnerabilities in the application. Exploitation could lead to unauthorized access to sensitive data and the potential for data breaches.

This vulnerability is particularly concerning due to its potential blast radius. If exploited, it could allow attackers to gain control over the application's environment, leading to further attacks on internal systems.

With a CVSS score of 8.1, this vulnerability falls within the high-severity range, necessitating immediate attention from organizations using the affected system. The lack of known exploits does not diminish the urgency of implementing mitigations.

Affected Versions

The vulnerability affects ThemeREX Le Truffe in all versions prior to the patch, specifically up to version 1.1.7.

Mitigation & Remediation

Organizations should prioritize patching the affected version of ThemeREX Le Truffe as soon as possible to eliminate the vulnerability. If a patch is unavailable, consider implementing workarounds such as restricting file inclusion capabilities in the PHP configuration.

For further guidance on enhancing security practices, organizations may consider engaging in penetration testing to uncover and address similar vulnerabilities.

Detection Guidance

To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual file inclusion attempts, as well as changes to sensitive files. Behavioral anomalies that deviate from normal application operations should also be flagged.

AppSecure Threat Intelligence Insight
