CVE-2025-69034 is a vulnerability classified as 'Improper Control of Filename for Include/Require Statement in PHP Program,' commonly known as a Remote File Inclusion (RFI) flaw, found in the Mikado-Themes Lekker WordPress theme. This vulnerability arises because the theme does not properly validate or sanitize input used in PHP include or require statements, allowing an attacker with low privileges to specify arbitrary files to be included and executed by the PHP interpreter. The affected versions include all releases up to and including version 1.8. The vulnerability requires the attacker to have some level of authentication (low privileges) but does not require user interaction, making exploitation feasible in many scenarios where an attacker can register or gain minimal access to the WordPress backend. The CVSS v3.1 score of 8.1 reflects a high severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality and integrity (C:H/I:H), but no impact on availability (A:N). Exploiting this vulnerability can lead to remote code execution, allowing attackers to run arbitrary PHP code, potentially leading to full site compromise, data theft, or use of the server as a pivot point for further attacks. No public exploits are currently known, but the vulnerability is published and should be considered a serious risk. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps.

For European organizations, the impact of CVE-2025-69034 can be severe, especially for those relying on WordPress sites using the Mikado-Themes Lekker theme. Successful exploitation can lead to unauthorized disclosure of sensitive data, including customer information and internal documents, compromising confidentiality. Integrity of website content and backend data can be altered or destroyed, potentially damaging brand reputation and trust. Although availability is not directly impacted, attackers could leverage the compromised server to launch further attacks, including lateral movement within networks or hosting malicious content. Given the widespread use of WordPress across Europe, organizations in sectors such as e-commerce, media, and government are particularly at risk. The vulnerability's requirement for low privileges means that even minor user accounts or compromised credentials can be leveraged for exploitation, increasing the attack surface. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score indicates that the threat could escalate rapidly once exploit code becomes available.

1. Immediate action should be to monitor official Mikado-Themes channels for patches or updates addressing this vulnerability and apply them as soon as they are released. 2. Until a patch is available, perform a manual code review of the Lekker theme's PHP files to identify and restrict any dynamic include or require statements, ensuring they only accept safe, whitelisted file paths. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests attempting to exploit file inclusion, focusing on parameters that influence file paths. 4. Restrict user privileges rigorously, ensuring that only trusted users have access to areas of the WordPress backend that could be leveraged for exploitation. 5. Employ PHP configuration hardening, such as disabling allow_url_include and restricting open_basedir to limit file inclusion to designated directories. 6. Conduct regular security audits and vulnerability scans on WordPress installations to detect any signs of compromise. 7. Educate administrators and developers about the risks of insecure file inclusion and encourage best practices in theme development and deployment.
