CVE-2025-58947 is a Local File Inclusion (LFI) vulnerability found in the axiomthemes Athos PHP theme, affecting versions up to 1.9. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements, allowing an attacker to manipulate the input to include arbitrary files from the server's filesystem. This can lead to disclosure of sensitive files such as configuration files, password files, or application source code, and in some cases, it may allow remote code execution if the attacker can include files containing malicious PHP code. The flaw is due to insufficient validation or sanitization of user-supplied input that controls the file path in the include/require statement. Although no public exploits are currently known, the vulnerability is critical because it can be exploited remotely without authentication, simply by sending crafted HTTP requests to the affected web application. The vulnerability affects websites using the Athos theme, which is a PHP-based theme likely used in WordPress or similar CMS platforms. The lack of a patch link indicates that a fix may not yet be publicly available, increasing the urgency for organizations to implement temporary mitigations. The vulnerability was reserved in September 2025 and published in December 2025, indicating recent discovery. Since the CVSS score is not assigned, the severity must be inferred from the nature of the vulnerability and its impact potential.

For European organizations, the impact of CVE-2025-58947 can be significant. Exploitation could lead to unauthorized disclosure of sensitive internal files, including credentials, configuration data, or proprietary source code, compromising confidentiality. If attackers manage to include files with executable PHP code, they could achieve remote code execution, leading to full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks. This can disrupt business operations, damage reputation, and result in regulatory penalties under GDPR if personal data is exposed. Organizations running websites or web applications with the vulnerable Athos theme are at risk, especially those in sectors with high web presence such as e-commerce, media, and government services. The vulnerability's remote exploitation without authentication increases the attack surface, making it easier for attackers to target European entities. Additionally, the lack of known exploits in the wild currently provides a window for proactive defense, but this may change rapidly once exploit code becomes available.

1. Monitor vendor announcements closely and apply official patches or updates for the Athos theme immediately once released. 2. Until patches are available, implement strict input validation and sanitization on all parameters controlling file inclusion paths to prevent manipulation. 3. Use web application firewalls (WAFs) with rules specifically designed to detect and block LFI attack patterns targeting include/require parameters. 4. Restrict PHP include paths using open_basedir or similar PHP configuration directives to limit accessible directories. 5. Disable unnecessary PHP functions such as allow_url_include to reduce remote inclusion risks. 6. Conduct thorough code reviews and penetration testing focusing on file inclusion points in the application. 7. Monitor web server logs for suspicious requests attempting to traverse directories or include unexpected files. 8. Educate developers and administrators about secure coding practices related to file inclusion and input handling. 9. Consider isolating vulnerable web applications in segmented network zones to limit lateral movement if compromised.
