CVE-2026-22413 is a Local File Inclusion (LFI) vulnerability found in the Mikado-Themes Malgré WordPress theme, affecting versions up to 1.0.3. The vulnerability arises from improper control of the filename parameter used in PHP include or require statements, which allows an attacker to manipulate the input to include arbitrary files from the server. This can lead to unauthorized disclosure of sensitive files, such as configuration files or source code, and potentially enable remote code execution if combined with other vulnerabilities or writable file locations. The flaw does not require authentication or user interaction, increasing the risk of automated exploitation. Despite no known public exploits at this time, the vulnerability is significant because LFI issues are commonly leveraged in web application attacks to escalate privileges or pivot within compromised environments. The lack of a CVSS score indicates the need for a severity assessment based on technical impact and exploitability. The vulnerability affects a widely used WordPress theme, which is popular among websites globally, increasing the potential attack surface. No official patches or mitigation links have been published yet, emphasizing the need for immediate attention from site administrators and developers.

The impact of CVE-2026-22413 is substantial for organizations using the Mikado-Themes Malgré WordPress theme. Successful exploitation can lead to unauthorized access to sensitive files, including credentials, configuration files, and application source code, compromising confidentiality. Attackers may also execute arbitrary code or commands if they can include files containing malicious payloads, threatening system integrity and availability. This can result in website defacement, data breaches, or the deployment of malware such as web shells. The vulnerability can be exploited remotely without authentication, increasing the risk of widespread attacks, especially on publicly accessible websites. Organizations relying on this theme for their web presence may face reputational damage, regulatory penalties, and operational disruptions if exploited. The absence of known exploits currently provides a window for proactive mitigation, but the risk remains high given the common exploitation of LFI vulnerabilities in the wild.

To mitigate CVE-2026-22413, organizations should immediately update the Mikado-Themes Malgré theme to a patched version once available. Until a patch is released, administrators should implement strict input validation and sanitization on any user-supplied parameters that influence file inclusion. Employing web application firewalls (WAFs) with rules targeting LFI attack patterns can help detect and block exploitation attempts. Restricting PHP's file inclusion functions by disabling allow_url_include and using open_basedir restrictions can limit the directories accessible for inclusion. Regularly auditing web server and application logs for suspicious activity related to file inclusion attempts is recommended. Additionally, isolating the web server environment and applying the principle of least privilege to file system permissions can reduce the impact of a successful attack. Organizations should also consider monitoring threat intelligence feeds for emerging exploits targeting this vulnerability to respond promptly.
