CVE-2026-28049 identifies a Local File Inclusion (LFI) vulnerability in the ThemeREX Police Department WordPress theme, versions up to 2.17. 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 file path input, causing the application to include unintended files from the server. Such an LFI vulnerability can lead to disclosure of sensitive information, such as configuration files, source code, or credentials stored on the server. In some cases, it may also facilitate remote code execution if combined with other vulnerabilities or if the attacker can upload malicious files. The vulnerability is classified as a PHP Remote File Inclusion type but specifically manifests as Local File Inclusion due to improper input validation. No CVSS score has been assigned yet, and no official patches or known exploits have been reported at the time of publication. The vulnerability affects the Police Department theme developed by ThemeREX, a product used primarily in WordPress environments, which are widely deployed globally. The lack of patch availability necessitates immediate attention to mitigate risk. Attackers do not require user interaction, and exploitation may not require authentication depending on the theme’s configuration, increasing the threat level. The vulnerability was reserved and published in early 2026, indicating recent discovery and disclosure.

The impact of CVE-2026-28049 is significant for organizations using the ThemeREX Police Department WordPress theme. Successful exploitation can lead to unauthorized disclosure of sensitive server files, including configuration files, database credentials, or application source code, compromising confidentiality. Attackers may also leverage this vulnerability to execute arbitrary code or pivot to further attacks within the network, threatening integrity and availability. Since WordPress is a widely used CMS globally, many organizations, including government, law enforcement, and private sector entities using this theme, could be affected. The vulnerability could facilitate data breaches, defacement, or full server compromise. The absence of a patch increases exposure time, and automated scanning tools could be developed to identify vulnerable installations, raising the risk of widespread exploitation. Organizations with public-facing websites running this theme are particularly at risk, as attackers can exploit the vulnerability remotely without user interaction or authentication in many cases. The impact extends to reputational damage, regulatory penalties, and operational disruption.

To mitigate CVE-2026-28049, organizations should immediately audit their WordPress installations to identify the use of the ThemeREX Police Department theme, especially versions up to 2.17. Until an official patch is released, apply the following specific mitigations: 1) Restrict access to vulnerable PHP files by implementing web server rules (e.g., .htaccess or nginx configurations) to block direct access to include files or directories used by the theme. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests attempting to manipulate include parameters. 3) Disable or restrict PHP functions such as include(), require(), and file inclusion functions if not essential or use PHP configuration directives like open_basedir to limit file system access. 4) Conduct code reviews and, if possible, modify the theme code to sanitize and validate all inputs controlling file paths, enforcing strict whitelisting of allowable files. 5) Monitor logs for unusual file inclusion attempts or errors indicating exploitation attempts. 6) Maintain regular backups and prepare incident response plans in case of compromise. 7) Stay alert for official patches or updates from ThemeREX and apply them promptly once available. These targeted measures go beyond generic advice by focusing on the specific nature of the vulnerability and the environment it affects.
