CVE-2026-22414 identifies a Local File Inclusion (LFI) vulnerability in the Mikado-Themes Marra WordPress theme, specifically due to improper control over the filename parameter used in PHP include or require statements. This vulnerability arises when user-supplied input is not properly validated or sanitized before being used to include files on the server. An attacker can exploit this flaw by manipulating the filename parameter to include arbitrary files from the server's filesystem. This can lead to information disclosure, such as reading configuration files or source code, and potentially remote code execution if combined with other vulnerabilities or writable file locations. The affected versions are up to and including 1.2, with no patch currently linked or available. The vulnerability was reserved in early January 2026 and published in March 2026. No known exploits are reported in the wild, and no CVSS score has been assigned yet. The issue is critical because PHP include/require statements are commonly used in WordPress themes to modularize code, and improper validation can lead to severe security consequences. The lack of a patch means users must either apply manual mitigations or monitor for updates from Mikado-Themes. Since this vulnerability affects a WordPress theme, it targets websites running WordPress with this specific theme installed, which may be used globally but more prevalent in regions with high WordPress adoption.

The impact of CVE-2026-22414 can be significant for organizations running websites with the Mikado-Themes Marra theme. Exploitation of this LFI vulnerability can lead to unauthorized disclosure of sensitive files such as configuration files containing database credentials, user data, or other sensitive information. In some cases, attackers may chain this vulnerability with others to achieve remote code execution, leading to full server compromise. This can result in data breaches, defacement, malware distribution, or use of the compromised server as a pivot point for further attacks. Organizations relying on the affected theme for their web presence risk reputational damage, loss of customer trust, and potential regulatory penalties if sensitive data is exposed. Since WordPress powers a large portion of the internet, and themes like Marra are widely used, the scope of affected systems could be broad. The absence of known exploits currently limits immediate risk, but the vulnerability remains a serious threat if weaponized. The impact is heightened for organizations with sensitive or critical web applications using the affected theme.

To mitigate CVE-2026-22414, organizations should take the following specific actions: 1) Immediately check if their WordPress installations use the Mikado-Themes Marra theme version 1.2 or earlier and plan to upgrade to a patched version once released by the vendor. 2) Until an official patch is available, review the theme’s PHP files that handle include/require statements and implement strict input validation and sanitization to ensure only allowed filenames or paths are included. 3) Employ allowlisting of file paths and disable dynamic inclusion of files based on user input wherever possible. 4) Restrict file permissions on the web server to limit access to sensitive files and directories. 5) Monitor web server logs for suspicious requests attempting to exploit file inclusion. 6) Use Web Application Firewalls (WAFs) with rules designed to detect and block LFI attack patterns targeting PHP include parameters. 7) Regularly back up website data and configurations to enable quick recovery if compromise occurs. 8) Educate development and security teams about secure coding practices related to file inclusion in PHP. These measures go beyond generic advice by focusing on theme-specific code review and proactive monitoring.
