CVE-2026-28063 is a Local File Inclusion (LFI) vulnerability found in the ThemeREX Asia Garden WordPress theme, versions up to 1.3.1. The vulnerability arises from improper validation or control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the input controlling which file is included, enabling them to include arbitrary files from the server's filesystem. Such an inclusion can lead to disclosure of sensitive files like configuration files, password stores, or other critical data. In some cases, LFI can be leveraged to execute arbitrary code if combined with other vulnerabilities or by including files with malicious content. The vulnerability does not require authentication, increasing its risk profile. No CVSS score has been assigned yet, and no known exploits are publicly available. The issue was reserved and published in early 2026, with no official patches or updates announced by ThemeREX at the time of this report. The vulnerability specifically affects the Asia Garden theme, which is used primarily in hospitality and tourism-related websites built on WordPress. The lack of patch links suggests that users must rely on manual mitigation or monitoring until an official fix is released.

The primary impact of CVE-2026-28063 is the potential exposure of sensitive server-side files, which can lead to information disclosure and facilitate further attacks such as privilege escalation or remote code execution. Organizations running websites with the Asia Garden theme are at risk of having their server files accessed by unauthorized parties, potentially exposing credentials, configuration data, or other sensitive information. This can compromise the confidentiality and integrity of the affected systems. Additionally, attackers might chain this vulnerability with others to execute malicious code, leading to full system compromise. The ease of exploitation without authentication increases the threat level, especially for publicly accessible websites. The hospitality and tourism sectors, which often use this theme, may face reputational damage and regulatory consequences if customer data is exposed. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant risk until patched.

1. Immediately audit all WordPress installations using the ThemeREX Asia Garden theme to identify affected versions (<= 1.3.1). 2. Disable or restrict access to vulnerable endpoints or parameters that control file inclusion until a patch is available. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests attempting to manipulate include/require parameters. 4. Employ strict input validation and sanitization on any user-controllable inputs related to file paths to prevent directory traversal or arbitrary file inclusion. 5. Monitor server logs for unusual file access patterns indicative of LFI exploitation attempts. 6. Keep all WordPress themes and plugins updated and subscribe to vendor security advisories for timely patch releases. 7. If possible, isolate the web server environment to limit the impact of any file inclusion exploitation. 8. Consider deploying runtime application self-protection (RASP) solutions to detect and block exploitation attempts in real-time. 9. Educate development and security teams about the risks of insecure file inclusion and secure coding practices to prevent similar vulnerabilities.
