CVE-2026-28007 identifies a Local File Inclusion (LFI) vulnerability in the ThemeREX Coinpress WordPress theme, specifically versions up to and including 1.0.14. The vulnerability stems from insufficient validation or sanitization of user-supplied input used in PHP include or require statements. This improper control allows an attacker to manipulate the filename parameter, causing the application to include unintended files from the local filesystem. Such an LFI flaw can be leveraged to disclose sensitive files such as configuration files, password stores, or logs, potentially revealing credentials or other critical information. In some cases, LFI can be chained with other vulnerabilities to achieve remote code execution (RCE), enabling full system compromise. The vulnerability was reserved and published in early 2026, with no CVSS score assigned yet and no known public exploits. The affected product, Coinpress, is a theme developed by ThemeREX, widely used in cryptocurrency-related WordPress sites. The lack of patch links indicates that a fix may not yet be available, increasing the urgency for mitigation. The vulnerability requires no authentication and can be triggered remotely, increasing its risk profile.

The impact of CVE-2026-28007 is significant for organizations using the Coinpress theme on WordPress sites, particularly those in the cryptocurrency sector. Successful exploitation can lead to unauthorized disclosure of sensitive files, including credentials and configuration data, which can facilitate further attacks. In worst-case scenarios, attackers may achieve remote code execution, allowing them to execute arbitrary commands, install malware, or pivot within the network. This can result in data breaches, service disruptions, reputational damage, and financial loss. Given the theme's focus on cryptocurrency, targeted attacks could also lead to theft of digital assets or compromise of transaction integrity. The vulnerability's remote and unauthenticated nature increases the attack surface, making it attractive to opportunistic attackers and advanced threat actors alike. Organizations worldwide that rely on Coinpress are at risk until mitigations or patches are applied.

To mitigate CVE-2026-28007, organizations should immediately audit their WordPress installations to identify the use of the Coinpress theme, particularly versions up to 1.0.14. Until an official patch is released by ThemeREX, administrators should consider temporarily disabling or replacing the theme to prevent exploitation. Implement strict input validation and sanitization on any user-controllable parameters that influence file inclusion paths. Employ Web Application Firewalls (WAFs) with rules designed to detect and block attempts to exploit LFI vulnerabilities, such as suspicious include path manipulations. Restrict file system permissions to limit the web server's access to sensitive files, minimizing the impact of potential LFI exploitation. Monitor web server logs for anomalous requests that attempt to include local files or access sensitive paths. Stay alert for updates from ThemeREX and apply patches promptly once available. Additionally, conduct regular security assessments and penetration testing focused on file inclusion vulnerabilities to proactively identify and remediate similar issues.
