CVE-2026-22427 is a Local File Inclusion (LFI) vulnerability found in the Mikado-Themes GoTravel WordPress theme, affecting versions up to 2.1. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the input to these statements, causing the server to include unintended local files. Such inclusion can lead to disclosure of sensitive files (e.g., configuration files, password stores) or potentially enable remote code execution if combined with other vulnerabilities or writable file locations. The vulnerability is categorized as an improper control of filename for include/require statements, a common PHP security issue. No CVSS score has been assigned yet, and no patches or known exploits are currently documented. The vulnerability was reserved in early 2026 and published in March 2026. The GoTravel theme is used primarily on WordPress sites, which are widely deployed globally, increasing the potential attack surface. Exploitation does not require authentication, making it accessible to unauthenticated attackers, and may require user interaction depending on how the theme processes input parameters. The lack of a patch means that affected sites remain vulnerable until updates or mitigations are applied.

The impact of CVE-2026-22427 can be significant for organizations using the GoTravel theme on WordPress. Successful exploitation can lead to unauthorized disclosure of sensitive server files, including configuration files containing database credentials or other secrets, which can compromise the confidentiality of data. In some scenarios, attackers might leverage this vulnerability to execute arbitrary code on the server, leading to full system compromise, data loss, or defacement. The vulnerability affects the integrity of the system by allowing attackers to influence which files are included and potentially execute malicious code. Availability could also be impacted if attackers use the vulnerability to disrupt services or crash the server. Since WordPress powers a large portion of websites worldwide, and Mikado-Themes is a known theme vendor, the scope of affected systems is broad. Organizations with public-facing WordPress sites using this theme are at risk, especially if they have not applied any custom mitigations. The lack of authentication requirement lowers the barrier to exploitation, increasing the threat level. Although no known exploits are currently reported, the vulnerability's nature makes it a likely target for attackers once publicized.

To mitigate CVE-2026-22427, organizations should immediately audit their WordPress installations to identify if the GoTravel theme version 2.1 or earlier is in use. If so, they should consider temporarily disabling the theme or restricting access to affected endpoints until a patch is available. Implementing Web Application Firewall (WAF) rules to block suspicious requests attempting to manipulate include parameters can reduce exposure. Restricting file permissions on the server to limit access to sensitive files can minimize the impact of file inclusion. Monitoring web server logs for unusual requests targeting include or require parameters can help detect exploitation attempts early. Developers should review and sanitize all user inputs that influence file inclusion, employing whitelisting of allowed files rather than blacklisting or direct user input. Once the vendor releases a patch, immediate application of the update is critical. Additionally, organizations should ensure their WordPress core, themes, and plugins are regularly updated and follow secure coding practices to prevent similar vulnerabilities.
