CVE-2025-58941 is a Remote File Inclusion (RFI) vulnerability found in the axiomthemes Fabric PHP theme, affecting versions up to 1.5.0. The vulnerability arises from improper validation or control of filenames passed to PHP's include or require statements. This flaw enables attackers to supply a crafted filename parameter that points to a remote malicious file, which the PHP interpreter then includes and executes. The consequence is the potential execution of arbitrary code on the affected server, leading to a compromise of confidentiality and integrity. The CVSS 3.1 base score of 8.2 indicates a high-severity issue with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The scope is unchanged (S:U), with high impact on confidentiality (C:H), low impact on integrity (I:L), and no impact on availability (A:N). The vulnerability does not require authentication, making it highly exploitable remotely. Although no public exploits are currently known, the nature of RFI vulnerabilities historically makes them attractive targets for attackers to deploy web shells, steal data, or pivot within networks. The affected product, Fabric by axiomthemes, is a PHP-based theme used in web applications, which may be integrated into various CMS or custom PHP setups. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps.

For European organizations, this vulnerability poses a significant risk, especially for those running web applications using the Fabric theme in PHP environments. Successful exploitation can lead to unauthorized code execution, data breaches, and potential lateral movement within corporate networks. Confidential information could be exfiltrated, and integrity of web content or backend systems could be compromised. Although availability is not directly impacted, the indirect effects of a breach—such as reputational damage, regulatory fines under GDPR, and operational disruptions—can be severe. Organizations in sectors with high web presence, such as e-commerce, media, and government services, are particularly vulnerable. The ease of exploitation without authentication increases the threat level, making automated attacks feasible. The absence of known exploits in the wild provides a window for proactive defense, but also means attackers may be developing exploits. European entities must consider the regulatory implications of a breach involving personal data and ensure compliance with data protection laws.

1. Immediately audit all web applications using the Fabric theme to identify affected versions (<=1.5.0). 2. Disable PHP's allow_url_include directive in php.ini to prevent remote file inclusion (set allow_url_include=Off). 3. Implement strict input validation and sanitization on all parameters that influence file inclusion, using whitelisting approaches where possible. 4. Employ web application firewalls (WAFs) with rules targeting RFI attack patterns to detect and block malicious requests. 5. Monitor web server and application logs for unusual include/require requests or unexpected outbound connections. 6. Isolate vulnerable web applications in segmented network zones to limit lateral movement if compromised. 7. Engage with axiomthemes or trusted security vendors for patches or updates as soon as they become available. 8. Conduct regular security assessments and penetration testing focused on file inclusion vulnerabilities. 9. Educate developers and administrators on secure coding practices related to file inclusion and PHP configuration. 10. Consider temporary removal or replacement of the Fabric theme if immediate patching is not feasible.
