The CVE-2026-22412 vulnerability represents a critical PHP Remote File Inclusion flaw that exists within the Mikado-Themes Eona eona theme version 1.3 and earlier. This vulnerability stems from improper control of filename parameters in include/require statements, creating a pathway for attackers to execute arbitrary code through malicious file inclusion techniques. The flaw specifically impacts the theme's handling of user-supplied input in file inclusion contexts, allowing remote attackers to manipulate the include/require functionality to load and execute arbitrary PHP files from remote servers or local filesystem locations.
The technical implementation of this vulnerability occurs when the Eona theme fails to properly validate or sanitize user input before using it in include/require statements. This allows an attacker to inject malicious filenames or URLs that bypass normal security controls. When the vulnerable PHP code processes user-supplied parameters and directly incorporates them into include/require functions without adequate sanitization, it creates an environment where remote code execution becomes possible. The vulnerability operates at the application layer and leverages the inherent capabilities of PHP's include/require functions to load and execute code from specified locations.
The operational impact of this vulnerability is severe as it provides attackers with the ability to execute arbitrary code on the affected system. This can lead to complete system compromise, data exfiltration, and persistent access to the target environment. Attackers can leverage this vulnerability to upload backdoors, establish command and control channels, or perform further reconnaissance activities within the compromised network. The local file inclusion aspect means that attackers can potentially access sensitive files on the server, including configuration files, database credentials, and other critical system information that may be stored locally.
Security controls and industry standards such as CWE-98 and CWE-88 directly relate to this vulnerability, as they address improper control of filename for include/require statements and improper neutralization of special elements in filenames. The ATT&CK framework categorizes this under technique T1059.007 for command and scripting interpreter, and T1078 for valid accounts, as attackers can leverage this vulnerability to establish persistent access and execute malicious commands. Organizations should implement strict input validation, disable remote file inclusion features, and ensure proper file path sanitization to prevent exploitation of this vulnerability.
Mitigation strategies include immediately updating to the latest version of the Eona theme where this vulnerability has been patched, implementing proper input validation and sanitization for all user-supplied parameters, and configuring PHP settings to disable remote file inclusion. Network segmentation and monitoring should be implemented to detect suspicious file inclusion patterns, while regular security audits should verify that all include/require statements properly validate file paths. Additionally, organizations should consider implementing web application firewalls and security monitoring solutions that can detect and block malicious file inclusion attempts. The vulnerability highlights the importance of proper parameter validation and input sanitization in preventing remote code execution attacks that can compromise entire systems.
