CVE-2025-69081 is a Remote File Inclusion (RFI) vulnerability classified under CWE-98, found in the ThemeREX Group's Hope WordPress theme (versions up to 3.0.0). The vulnerability arises due to improper control of filenames used in PHP include or require statements, allowing an attacker to manipulate the input to these statements to include remote files. This can lead to arbitrary PHP code execution on the server hosting the vulnerable theme. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, although it has a high attack complexity, likely due to the need to identify vulnerable endpoints or specific parameters. Successful exploitation can compromise the confidentiality, integrity, and availability of the affected system, potentially allowing attackers to execute malicious code, steal sensitive data, or disrupt services. The CVSS v3.1 base score is 8.1, reflecting high severity with network attack vector, no privileges required, no user interaction, and high impact on all security properties. No patches or fixes are currently linked, and no known exploits are reported in the wild, indicating a need for proactive mitigation. The vulnerability primarily affects PHP-based WordPress sites using the Hope theme, commonly deployed by charities and NGOs.

For European organizations, particularly NGOs, charities, and non-profits that rely on WordPress and the Hope theme, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive donor information, financial data, and internal communications, severely impacting confidentiality. Integrity could be compromised by attackers injecting malicious code or altering website content, damaging reputation and trust. Availability may also be affected if attackers deploy denial-of-service payloads or backdoors. Given the theme's focus on charity websites, the impact extends to public trust and compliance with data protection regulations such as GDPR. The lack of authentication requirement and remote exploitability increase the risk of widespread attacks. European organizations with limited cybersecurity resources may be particularly vulnerable to exploitation and subsequent data breaches or service disruptions.

1. Immediately identify and inventory all WordPress installations using the Hope theme, especially versions up to 3.0.0. 2. Remove or disable the vulnerable theme until a security patch is released by ThemeREX Group. 3. Apply strict input validation and sanitization on any parameters used in include/require statements to prevent injection of remote file paths. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block Remote File Inclusion attempts targeting PHP include functions. 5. Monitor web server logs for suspicious requests attempting to include remote files or unusual URL parameters. 6. Restrict outbound HTTP/HTTPS requests from the web server to prevent fetching malicious remote files. 7. Keep WordPress core, themes, and plugins updated regularly and subscribe to security advisories from ThemeREX and WordPress security communities. 8. Conduct regular security audits and penetration testing focusing on PHP file inclusion vulnerabilities. 9. Educate site administrators on the risks of installing untrusted themes and the importance of timely updates.
