CVE-2025-58958 is a Remote File Inclusion (RFI) vulnerability found in the ThemeMove SmilePure WordPress theme, specifically affecting versions prior to 1.8.5. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the input to these statements, causing the application to include and execute arbitrary remote PHP code. The vulnerability does not require authentication or user interaction, making it remotely exploitable over the network with low attack complexity. The CVSS v3.1 score of 8.2 reflects a high severity, with network attack vector, no privileges required, no user interaction, and a significant impact on integrity and some impact on confidentiality, but no impact on availability. Exploiting this vulnerability can lead to unauthorized code execution, data manipulation, and potential full compromise of the affected web server. Although no known exploits are currently reported in the wild, the nature of RFI vulnerabilities historically makes them attractive targets for attackers aiming to deploy web shells, steal data, or pivot within networks. The vulnerability affects the SmilePure theme, which is used in WordPress installations, a widely adopted CMS platform globally. The lack of patch links suggests that a fixed version (1.8.5 or later) is either newly released or imminent. The vulnerability was reserved in early September 2025 and published in late October 2025, indicating recent discovery and disclosure.

For European organizations, this vulnerability poses a significant risk especially for those relying on the SmilePure theme for their WordPress websites. Successful exploitation can lead to unauthorized remote code execution, allowing attackers to manipulate website content, steal sensitive data, or establish persistent backdoors. This can result in data breaches affecting customer information, intellectual property theft, defacement of public-facing websites, and disruption of business operations. Given the high adoption of WordPress in Europe, particularly among SMEs and e-commerce platforms, the potential attack surface is considerable. Additionally, compromised websites can be used as launchpads for further attacks within corporate networks or to distribute malware to visitors, amplifying the impact. Regulatory frameworks like GDPR impose strict data protection requirements, and exploitation could lead to significant legal and financial consequences for affected organizations. The absence of known exploits in the wild currently offers a window for proactive mitigation, but the vulnerability's characteristics suggest that it could be rapidly weaponized once exploit code becomes publicly available.

1. Immediately update the SmilePure theme to version 1.8.5 or later once the patch is available to eliminate the vulnerability. 2. Until patching is possible, implement strict input validation and sanitization on any parameters used in include or require statements to prevent malicious input. 3. Configure PHP settings to disable allow_url_include and allow_url_fopen directives to prevent inclusion of remote files. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block attempts to exploit RFI vulnerabilities, including suspicious URL patterns and payloads. 5. Restrict file inclusion paths using PHP's open_basedir directive to limit accessible directories. 6. Conduct thorough code reviews and security audits of custom themes and plugins to identify similar vulnerabilities. 7. Monitor web server logs for unusual requests indicative of exploitation attempts. 8. Educate web administrators and developers about secure coding practices related to file inclusion. 9. Maintain regular backups of website data and configurations to enable rapid recovery in case of compromise. 10. Consider deploying runtime application self-protection (RASP) solutions to detect and block malicious behavior in real time.
