A high-severity vulnerability, identified as CVE-2025-67934, has been discovered in the Mikado-Themes Wellspring product. This flaw allows an unauthenticated attacker to trick the web server into including and potentially executing arbitrary files on the server, which could lead to sensitive information disclosure, data theft, or a complete system compromise.

This vulnerability is a Local File Inclusion (LFI) flaw within the Mikado-Themes Wellspring software. The application fails to properly sanitize user-supplied input that is used to construct a file path for an include or require statement in its PHP code. An unauthenticated remote attacker can exploit this by crafting a malicious request, typically manipulating a URL parameter with path traversal characters (../), to force the application to include and process a file from an arbitrary location on the server's local filesystem. Successful exploitation could allow the attacker to read the contents of sensitive files (e.g., wp-config.php, /etc/passwd) or, if a file containing PHP code can be included, achieve remote code execution in the security context of the web server process.

This vulnerability is rated as High severity with a CVSS score of 8.1. Exploitation of this flaw could have a significant negative impact on the business. Potential consequences include a data breach resulting from the theft of sensitive configuration files, application source code, or customer data. If an attacker achieves remote code execution, they could gain full control of the web server, leading to website defacement, installation of malware or ransomware, or using the compromised server to launch further attacks against the internal network. Such an incident could result in severe reputational damage, loss of customer trust, and potential regulatory fines.

Immediate Action: The primary remediation is to apply the security updates provided by the vendor across all affected systems immediately. Following patching, system administrators should actively monitor for any signs of exploitation attempts by reviewing web server access logs and security event logs for anomalous activity consistent with LFI attacks.

Proactive Monitoring: Organizations should enhance their monitoring capabilities to detect potential exploitation attempts. Review web server access logs for requests containing path traversal sequences (e.g., ../, %2e%2e%2f), references to common sensitive files (e.g., /etc/passwd, win.ini), or unusual file extensions in URL parameters. Intrusion Detection/Prevention Systems (IDS/IPS) and Web Application Firewalls (WAF) should be configured with rulesets designed to detect and block LFI attack patterns.

Compensating Controls: If immediate patching is not feasible, the following compensating controls can help mitigate the risk:

• Deploy a Web Application Firewall (WAF) with a strict ruleset to filter malicious requests containing path traversal patterns.
• Harden the server's PHP configuration by using the open_basedir directive to restrict the file paths that PHP can access.
• Enforce the principle of least privilege by ensuring the web server process runs with minimal permissions and cannot read sensitive system or configuration files outside of its web root.

Public Exploit Available: false

Given the high CVSS score of 8.1 and the critical impact of a successful exploit, this vulnerability poses a significant risk to the organization. Although this vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog, its severity and the ease with which it can be exploited warrant immediate attention. We strongly recommend that organizations prioritize the immediate deployment of the vendor-supplied security updates to all affected assets. If patching is delayed, the compensating controls outlined above must be implemented as a temporary measure while continuing to monitor for any signs of compromise.
