CVE-2025-49367 is a Local File Inclusion (LFI) vulnerability found in the AncoraThemes Monyxi WordPress theme, specifically affecting versions up to 1.1.8. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This lack of validation allows an attacker to manipulate the filename input to include arbitrary files from the server's filesystem. Exploiting this vulnerability can lead to disclosure of sensitive information such as configuration files, password files, or other critical data stored on the web server. In some cases, if combined with other vulnerabilities or misconfigurations, it may allow remote code execution. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although no public exploits are currently reported, the flaw is publicly disclosed and documented in the CVE database. The absence of a CVSS score suggests the need for a manual severity assessment. AncoraThemes is a known vendor of WordPress themes, and Monyxi is used primarily in creative and business websites. The vulnerability is due to insecure coding practices where user input is directly used in file inclusion functions without proper sanitization or validation, violating secure coding guidelines for PHP applications.

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive data, including credentials, internal configuration files, or customer information, potentially violating GDPR and other data protection regulations. If exploited, attackers could gain a foothold in the web server environment, leading to further lateral movement or persistent compromise. Organizations relying on the Monyxi theme for their websites, especially those in sectors such as e-commerce, media, and professional services, face reputational damage and operational disruption. The impact is heightened in Europe due to strict data privacy laws and the high adoption rate of WordPress-based websites. Additionally, compromised websites can be used to distribute malware or conduct phishing campaigns targeting European users. The lack of known exploits currently limits immediate widespread impact, but the public disclosure increases the risk of future exploitation attempts.

Organizations should immediately inventory their web assets to identify any use of the AncoraThemes Monyxi theme, particularly versions up to 1.1.8. Until an official patch is released, manual mitigation includes reviewing and hardening the theme’s PHP code to ensure all include/require statements validate and sanitize input parameters rigorously, restricting file inclusion to whitelisted paths only. Employ web application firewalls (WAFs) with rules to detect and block attempts to exploit LFI patterns. Regularly monitor web server logs for suspicious requests targeting file inclusion parameters. Implement strict file permissions on the web server to limit access to sensitive files. Educate development teams on secure coding practices to prevent similar vulnerabilities. Once a patch is available from AncoraThemes, apply it promptly. Additionally, consider isolating the web server environment and employing intrusion detection systems to detect anomalous behavior. Backup website data regularly to enable recovery in case of compromise.
