CVE-2026-28045 identifies a Local File Inclusion (LFI) vulnerability in the ThemeREX N7 | Golf Club Sports & Events WordPress theme, specifically versions up to 2.16.0. The vulnerability stems from improper control over the filename parameter used in PHP include or require statements. This allows an attacker to manipulate the input to include arbitrary local files on the web server. LFI vulnerabilities can lead to disclosure of sensitive information such as configuration files, source code, or credentials, and in some cases, can be leveraged to achieve remote code execution if combined with other vulnerabilities or misconfigurations. The root cause is insufficient input validation or sanitization on parameters controlling file inclusion. The vulnerability was reserved in late February 2026 and published in early March 2026, with no CVSS score assigned yet and no known exploits in the wild. The affected product is a WordPress theme used primarily for golf clubs and sports event websites, which may contain sensitive user data or administrative functions. The lack of a patch link indicates that a fix may not yet be publicly available, increasing the urgency for mitigation. Attackers exploiting this vulnerability do not require authentication, and exploitation can be performed remotely by sending crafted requests to the vulnerable PHP scripts. This vulnerability poses a significant risk to the confidentiality and integrity of affected systems and could lead to further compromise if exploited successfully.

The impact of CVE-2026-28045 on organizations worldwide can be substantial. Exploitation of this Local File Inclusion vulnerability can lead to unauthorized disclosure of sensitive files such as configuration files, database credentials, or private keys, compromising confidentiality. In some environments, attackers may leverage LFI to execute arbitrary code, leading to full system compromise, affecting integrity and availability. Organizations running websites using the vulnerable ThemeREX N7 | Golf Club Sports & Events theme risk data breaches, defacement, or use of their infrastructure for further attacks. This is particularly critical for organizations handling personal data, payment information, or proprietary business data. The ease of exploitation without authentication increases the threat level, enabling attackers to scan and target vulnerable sites en masse. Additionally, compromised sites can be used to distribute malware or phishing content, amplifying the impact beyond the initial victim. The absence of a patch at the time of disclosure further elevates risk, requiring immediate mitigation efforts to prevent exploitation.

To mitigate CVE-2026-28045, organizations should first verify if their WordPress sites use the ThemeREX N7 | Golf Club Sports & Events theme version 2.16.0 or earlier. If so, they should monitor the vendor's channels for official patches or updates and apply them promptly once available. In the interim, administrators should implement strict input validation and sanitization on any parameters controlling file inclusion to prevent manipulation. Employing Web Application Firewalls (WAFs) with rules targeting LFI attack patterns can help block malicious requests. Restricting PHP include paths using configuration directives (e.g., open_basedir) can limit file access to safe directories. Regularly auditing server logs for suspicious access patterns and scanning for known vulnerabilities is recommended. Additionally, isolating the web server environment and minimizing file permissions reduces the potential damage from exploitation. Backup critical data and have an incident response plan ready in case of compromise. Finally, consider replacing or removing the vulnerable theme if no timely patch is forthcoming.
