CVE-2025-58943 is a vulnerability classified as a Remote File Inclusion (RFI) issue in the axiomthemes Agricola PHP theme, specifically affecting versions up to and including 1.1.0. The root cause is improper control over the filename parameter used in PHP include or require statements, which allows an attacker to manipulate the input to include arbitrary files. This can lead to Local File Inclusion (LFI) or Remote File Inclusion, depending on the configuration, enabling attackers to execute arbitrary PHP code remotely or disclose sensitive files on the server. The vulnerability is particularly dangerous because it can be exploited without authentication and does not require user interaction, making automated exploitation feasible. Although no public exploits are currently documented, the nature of RFI vulnerabilities historically leads to rapid exploitation once disclosed. The affected product, Agricola by axiomthemes, is a PHP-based theme likely used in WordPress or similar CMS environments, often in agricultural or related industries. The lack of a CVSS score indicates the need for an expert severity assessment, which is high given the potential for full system compromise. The vulnerability was reserved in September 2025 and published in December 2025, but no patches or mitigations have been officially released yet. This vulnerability underscores the importance of secure coding practices around file inclusion and input validation in PHP applications.

For European organizations, the impact of CVE-2025-58943 can be severe. Exploitation could lead to arbitrary code execution on web servers running the vulnerable Agricola theme, resulting in full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks. Confidentiality is at risk as attackers may read sensitive files; integrity is compromised through code injection or modification; availability can be affected if attackers disrupt services or deploy ransomware. Organizations in agriculture, agritech, or rural business sectors using this theme are particularly vulnerable. Given the widespread use of PHP-based CMS platforms in Europe, especially WordPress, the attack surface is significant. The lack of authentication requirement and ease of exploitation increase the risk of automated mass exploitation campaigns. Additionally, compromised systems could be used to launch attacks on supply chains or critical infrastructure, which are strategic concerns in Europe. The absence of known exploits currently provides a window for mitigation, but rapid patching and monitoring are critical to prevent future incidents.

1. Immediately monitor for updates or patches from axiomthemes and apply them as soon as they become available. 2. Until a patch is released, disable remote file inclusion in PHP by setting 'allow_url_include=Off' in php.ini and ensure 'allow_url_fopen' is also disabled if not needed. 3. Implement strict input validation and sanitization on all parameters that influence file inclusion, using whitelisting approaches rather than blacklisting. 4. Restrict web server file system permissions to prevent the web server user from accessing sensitive files or directories. 5. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious file inclusion patterns or payloads. 6. Conduct code audits on custom or third-party themes/plugins to identify similar vulnerabilities. 7. Monitor web server logs for unusual requests attempting to exploit file inclusion. 8. Consider isolating or containerizing web applications to limit the blast radius of potential exploitation. 9. Educate developers and administrators on secure coding practices related to file inclusion and PHP configuration. 10. Backup critical data regularly and verify restoration procedures to mitigate impact in case of compromise.
