CVE-2025-49367 is a vulnerability classified as 'Improper Control of Filename for Include/Require Statement in PHP Program,' specifically affecting the AncoraThemes Monyxi WordPress theme versions up to 1.1.8. The vulnerability enables PHP Local File Inclusion (LFI), where an attacker can manipulate the filename parameter used in PHP include or require statements to load arbitrary local files on the web server. This can lead to unauthorized disclosure of sensitive files, execution of malicious code, or full system compromise depending on the server configuration and accessible files. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, but it has a high attack complexity, indicating some conditions must be met for successful exploitation. The CVSS v3.1 base score is 8.1, reflecting high impact on confidentiality, integrity, and availability. No known public exploits are reported yet, but the vulnerability is publicly disclosed and should be considered a significant risk. The lack of a patch link indicates that a fix may not yet be available, requiring organizations to implement interim mitigations. This vulnerability primarily affects web servers running the vulnerable Monyxi theme, which is used in WordPress content management systems, a widely deployed platform globally including Europe.

For European organizations, the impact of CVE-2025-49367 can be severe. Exploitation of this LFI vulnerability can lead to unauthorized access to sensitive configuration files, user data, or credentials stored on the server, resulting in data breaches and privacy violations under GDPR. Attackers may also execute arbitrary code or escalate privileges, potentially leading to full server compromise, defacement, or use of the server as a pivot point for further attacks within the network. This can disrupt business operations, damage reputation, and incur regulatory penalties. Given the widespread use of WordPress and AncoraThemes in Europe, especially among SMEs and content-driven businesses, the attack surface is significant. The high CVSS score reflects the potential for complete loss of confidentiality, integrity, and availability of affected systems. The absence of known exploits currently provides a window for proactive defense, but the risk of imminent exploitation remains high once exploit code becomes available.

European organizations should immediately inventory their WordPress installations to identify any running AncoraThemes Monyxi versions up to 1.1.8. Until a vendor patch is released, implement strict input validation and sanitization on any parameters controlling file inclusion. Employ web application firewalls (WAFs) with rules designed to detect and block LFI attack patterns, such as suspicious directory traversal or null byte injection attempts. Restrict PHP include paths using open_basedir and disable allow_url_include in PHP configurations to limit file inclusion scope. Regularly monitor logs for unusual file access or error messages indicative of exploitation attempts. Plan for rapid deployment of vendor patches once available and conduct thorough testing before applying updates. Additionally, consider isolating WordPress instances in segmented network zones to limit lateral movement if compromise occurs. Educate development and security teams about the risks of insecure file inclusion and enforce secure coding practices in custom themes and plugins.
