CVE-2025-62054 is a Remote File Inclusion (RFI) vulnerability found in the favethemes Houzez Theme - Functionality WordPress plugin, specifically in versions up to 4.1.8. The vulnerability stems from improper validation and control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to supply a crafted filename that points to a remote malicious file, which the server then includes and executes. Since PHP's include and require functions execute the included code, this can lead to arbitrary code execution on the web server hosting the vulnerable WordPress site. The vulnerability does not require authentication or user interaction, making it highly exploitable remotely. Although no public exploits are reported yet, the nature of RFI vulnerabilities historically leads to rapid exploitation once disclosed. The Houzez theme is widely used in real estate websites, which often handle sensitive client data and business operations, increasing the attractiveness of this target. The vulnerability affects all installations running the affected versions, and without a patch currently available, organizations remain exposed. The lack of a CVSS score indicates the need for an expert severity assessment, which here is critical due to the potential impact and ease of exploitation. The vulnerability highlights the importance of secure coding practices around file inclusion and input validation in PHP applications.

The impact of CVE-2025-62054 on European organizations can be severe. Successful exploitation allows attackers to execute arbitrary code on the web server, potentially leading to full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks. Real estate companies and property management firms using the Houzez theme may face exposure of sensitive client information, financial data, and internal business processes. Disruption of website availability could damage reputation and business continuity. Additionally, compromised servers could be enlisted in broader cybercrime activities such as hosting phishing sites or distributing malware. The ease of exploitation without authentication increases the risk of widespread attacks, especially against organizations that delay patching or lack robust web application firewalls. Given the critical role of real estate in many European economies, the threat could have cascading effects on trust and operational stability within the sector.

To mitigate CVE-2025-62054, organizations should immediately identify all WordPress installations using the Houzez Theme - Functionality plugin and verify their version. Until an official patch is released, manual mitigation steps include: (1) auditing and sanitizing all inputs that influence file inclusion parameters to ensure only local, trusted files are included; (2) disabling allow_url_include in PHP configurations to prevent remote file inclusion; (3) implementing strict web application firewall (WAF) rules to detect and block suspicious requests attempting to exploit file inclusion; (4) restricting file permissions to limit the execution of unauthorized scripts; (5) monitoring logs for unusual inclusion attempts or errors related to file inclusion; and (6) planning for immediate update to a patched version once available. Additionally, organizations should conduct regular security assessments of their WordPress environments and educate developers on secure coding practices related to file handling.
