CVE-2026-22402 is a vulnerability classified as improper control of filename for include/require statements in the PHP-based pavothemes Triply product, versions up to and including 2.4.7. This vulnerability allows remote file inclusion (RFI), where an attacker can manipulate the filename parameter used in PHP include or require functions to load and execute arbitrary remote code on the server. The vulnerability arises from insufficient validation or sanitization of user-supplied input that controls the file path, enabling attackers to specify external URLs or local files. Successful exploitation can lead to full system compromise, including unauthorized access to sensitive data, modification or deletion of files, and disruption of service. The CVSS v3.1 score is 7.5, indicating high severity, with attack vector being network-based, requiring low privileges but high attack complexity, no user interaction, and impacting confidentiality, integrity, and availability. No public exploits are known yet, but the vulnerability is published and should be treated as critical for affected environments. The lack of available patches at the time of reporting necessitates immediate risk mitigation through configuration hardening and monitoring. This vulnerability is particularly relevant for organizations using Triply as a content management or e-commerce platform, where web-facing PHP applications are common attack surfaces.

For European organizations, exploitation of CVE-2026-22402 could result in severe consequences including unauthorized disclosure of sensitive customer and business data, defacement or manipulation of web content, and potential full server takeover. This can lead to reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. Organizations relying on pavothemes Triply for critical web services or e-commerce platforms face risks of financial loss and erosion of customer trust. The network-based attack vector means attackers can exploit the vulnerability remotely without user interaction, increasing the likelihood of attacks. The requirement for low privileges but high attack complexity suggests that while exploitation is not trivial, skilled attackers or automated tools could succeed. The absence of known exploits currently provides a window for proactive defense, but the public disclosure increases the risk of future exploitation attempts. European sectors with high web presence such as retail, media, and public services are particularly vulnerable.

1. Monitor pavothemes and Triply vendor channels closely for official patches and apply them immediately upon release. 2. Until patches are available, disable PHP remote file inclusion by setting 'allow_url_include=Off' and 'allow_url_fopen=Off' in php.ini to prevent loading remote files. 3. Implement strict input validation and sanitization on all parameters controlling file paths, ensuring only expected local files can be included. 4. Employ web application firewalls (WAFs) configured to detect and block suspicious file inclusion patterns and anomalous HTTP requests. 5. Conduct thorough code reviews and security audits of customizations or plugins that interact with include/require statements. 6. Restrict file and directory permissions on web servers to limit the impact of potential exploitation. 7. Enable detailed logging and monitor for unusual file access or inclusion attempts to detect exploitation early. 8. Educate development and operations teams about secure coding practices related to file inclusion vulnerabilities.
