CVE-2025-58941 is a Remote File Inclusion (RFI) vulnerability identified in the axiomthemes Fabric product, a PHP-based theme or framework used in web applications. The vulnerability stems from improper control over the filename parameter used in PHP's include or require statements, which are functions that incorporate and execute code from specified files. When these filenames are not properly validated or sanitized, an attacker can manipulate the input to include arbitrary files, potentially from remote servers (RFI) or local files (LFI). This can lead to execution of malicious code within the context of the web server, allowing attackers to execute arbitrary PHP code, escalate privileges, steal sensitive data, or pivot within the network. The affected versions include all releases up to and including 1.5.0, with no specific earliest version identified. Although no public exploits are currently known, the nature of RFI vulnerabilities makes them highly exploitable, especially in internet-facing applications. The vulnerability was reserved in September 2025 and published in December 2025, but no CVSS score or patches have been released yet. The lack of patches means organizations must rely on temporary mitigations such as disabling remote file inclusion in PHP configurations (e.g., setting allow_url_include=Off), applying strict input validation, and monitoring for suspicious activity. This vulnerability is critical due to its potential to allow full system compromise without requiring authentication or user interaction.

For European organizations, the impact of CVE-2025-58941 can be severe. Exploitation could lead to unauthorized remote code execution, allowing attackers to take control of web servers hosting the Fabric theme. This compromises confidentiality by exposing sensitive data, integrity by allowing modification of files or databases, and availability by potentially causing denial of service or system crashes. Organizations running public-facing websites or applications using the affected Fabric versions are at high risk, especially those in sectors like e-commerce, government, finance, and media where web presence is critical. The breach could result in data leaks, reputational damage, regulatory penalties under GDPR, and operational disruptions. Since PHP is widely used across Europe, and many websites rely on third-party themes, the attack surface is significant. The absence of known exploits currently provides a window for proactive defense, but the ease of exploitation and critical impact necessitate urgent attention.

1. Immediately audit all web applications using axiomthemes Fabric and identify affected versions (<=1.5.0). 2. Apply vendor patches or updates as soon as they become available. 3. Until patches are released, disable remote file inclusion by setting 'allow_url_include=Off' in the PHP configuration (php.ini). 4. Implement strict input validation and sanitization on all parameters that influence file inclusion, ensuring only expected and safe filenames are accepted. 5. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious include/require attempts or unusual URL patterns. 6. Conduct regular code reviews and security testing focusing on file inclusion mechanisms. 7. Monitor logs for anomalous requests that attempt to exploit file inclusion vulnerabilities. 8. Educate developers and administrators about secure coding practices related to file handling in PHP. 9. Consider isolating or sandboxing web applications to limit the impact of potential exploitation. 10. Maintain up-to-date backups and incident response plans to quickly recover from any compromise.
