CVE-2026-28019 is a high-severity vulnerability classified as a PHP Remote File Inclusion in the ThemeREX Manoir theme. It allows for PHP Local File Inclusion due to improper control of the filename for include/require statements. This vulnerability affects versions of Manoir up to and including 1.11. With a CVSS score of 8.1, it poses significant risks to affected systems.
Risk to organizations includes potential unauthorized access to sensitive files and data, compromise of application integrity, and disruption of service availability. As this vulnerability remains deferred, organizations must remain vigilant and prioritize remediation in their patch management cycles.
Currently, there are no known exploits or public proof-of-concept (PoC) code available for this vulnerability. However, given its high severity and potential impact, organizations should prioritize patching immediately.
In light of the CVSS score and potential exploitation avenues, organizations utilizing the ThemeREX Manoir theme should assess their risk posture and take appropriate actions to mitigate exposure.
Vulnerability Details
The vulnerability results from improper control of the filename for include/require statements in PHP programs, leading to local file inclusion vulnerabilities. The CVSS 3.1 metrics indicate a high attack vector of NETWORK, high complexity, with no privileges or user interaction required, resulting in high impacts on confidentiality, integrity, and availability.
Affected versions are all versions prior to vendor patch, specifically versions up to and including 1.11. The CWE classification for this vulnerability is CWE-98, which indicates a 'Improper Control of Filename for Include/Require Statement'.
Technical Analysis
The root cause of this vulnerability lies in how the ThemeREX Manoir theme handles filenames for include or require statements without sufficient validation. Attackers may exploit this vulnerability by crafting requests that manipulate the filename parameter, potentially including sensitive files from the server.
The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely without being on the local network. The attack complexity is high, requiring knowledge of PHP and the specific theme implementation. No privileges are required, and no user interaction is needed, making exploitation more feasible.
The potential impact on confidentiality, integrity, and availability is significant, as successful exploitation can lead to unauthorized access to sensitive files, alteration of application behavior, and unavailability of services.
Risk & Impact Analysis
Organizations using the ThemeREX Manoir theme must recognize the real-world risks associated with this vulnerability. The potential blast radius includes unauthorized access to sensitive information and application integrity issues, which can have severe implications for business operations.
Given the CVSS score of 8.1, the urgency for remediation should be classified as high. Organizations should assess their deployment of the Manoir theme and prioritize patching based on their risk exposure.
As this vulnerability is not included in the KEV catalog, organizations must be proactive in monitoring their systems for potential exploitation and take necessary actions to mitigate risks.

Affected Versions
The affected versions of the ThemeREX Manoir theme are all versions prior to the vendor patch, specifically up to and including version 1.11.
Mitigation & Remediation
Organizations should prioritize patching the ThemeREX Manoir theme to address this vulnerability. The vendor should be consulted for the latest patch information. If an immediate patch is unavailable, organizations may implement workaround solutions such as restricting access to sensitive files and monitoring for unusual file inclusion behavior.
For further guidance on maintaining security, organizations should consider implementing configuration hardening practices and network controls.
Penetration testing can also be employed to assess the effectiveness of the mitigation measures implemented.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized access to sensitive files and any discrepancies in file inclusion requests. Behavioral anomalies should be investigated, focusing on unusual patterns in file access and inclusion.
Network signatures should be established to detect potential exploitation attempts. Regular audits and system changes should be documented and reviewed to identify any unauthorized modifications.
