CVE-2025-58958 is a Remote File Inclusion (RFI) vulnerability found in the ThemeMove SmilePure WordPress theme, affecting all versions prior to 1.8.5. The vulnerability arises from improper validation and control of filenames used in PHP include or require statements. Specifically, the theme allows an attacker to manipulate the filename parameter to include remote files, which can lead to arbitrary PHP code execution on the server. This type of vulnerability is particularly dangerous because it enables remote attackers to execute code without authentication or user interaction, potentially leading to full site compromise. The CVSS 3.1 base score of 8.2 reflects the network attack vector, low attack complexity, no privileges required, no user interaction, and a significant impact on integrity with limited confidentiality impact and no availability impact. Although no public exploits have been reported yet, the nature of RFI vulnerabilities makes them attractive targets for attackers aiming to deploy web shells, steal data, or pivot within compromised networks. The vulnerability affects the SmilePure theme, which is used primarily in WordPress environments, often for blogs, portfolios, or e-commerce sites. The lack of patch links suggests that users must obtain updates directly from the vendor or official repositories. The vulnerability was reserved in early September 2025 and published in late October 2025, indicating a recent disclosure.

For European organizations, the impact of CVE-2025-58958 can be significant, especially for those relying on WordPress sites using the SmilePure theme. Successful exploitation can lead to unauthorized code execution, allowing attackers to modify website content, steal sensitive user data, or deploy malware such as web shells and ransomware. This can damage organizational reputation, lead to data breaches under GDPR regulations, and cause operational disruptions. E-commerce platforms and media companies are particularly vulnerable due to the potential exposure of customer data and intellectual property. Additionally, compromised websites can be used as launchpads for further attacks within corporate networks or for distributing malware to visitors. The lack of required authentication and user interaction increases the risk of widespread exploitation. Given the high adoption of WordPress across Europe, organizations with outdated SmilePure themes are at elevated risk. The impact is compounded by the potential for regulatory fines and loss of customer trust following a breach.

1. Immediately update the SmilePure theme to version 1.8.5 or later, where the vulnerability is patched. 2. If immediate patching is not possible, implement strict input validation and sanitization on all parameters that influence file inclusion paths to prevent remote file references. 3. Configure PHP settings to disable allow_url_include and allow_url_fopen directives to prevent inclusion of remote files. 4. Employ a Web Application Firewall (WAF) with custom rules to detect and block suspicious requests attempting to exploit file inclusion vulnerabilities. 5. Restrict file inclusion paths using PHP's open_basedir directive to limit accessible directories. 6. Regularly audit WordPress themes and plugins for updates and vulnerabilities. 7. Monitor web server logs for unusual requests that may indicate exploitation attempts. 8. Educate development and IT teams about secure coding practices related to file inclusion. 9. Consider isolating WordPress environments to minimize lateral movement in case of compromise.
