CVE-2025-14856 is a code injection vulnerability identified in the y_project RuoYi framework, specifically affecting versions 4.8.0 and 4.8.1. The vulnerability is located in an unspecified function within the /monitor/cache/getnames endpoint, where improper sanitization or validation of an argument fragment allows an attacker to inject malicious code. This flaw enables remote attackers to execute arbitrary code on the affected system without requiring authentication or user interaction, increasing the attack surface significantly. The vulnerability was publicly disclosed shortly after its discovery, but no confirmed exploits in the wild have been reported to date. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability can lead to unauthorized code execution, potentially compromising system integrity, leaking sensitive data, or disrupting service availability. The lack of available patches at the time of disclosure necessitates interim mitigations such as input validation and network access controls. Given RuoYi's usage in enterprise Java applications, this vulnerability poses a risk to organizations relying on this framework for monitoring and caching functionalities.

For European organizations, exploitation of CVE-2025-14856 could result in unauthorized remote code execution, leading to potential data breaches, system manipulation, or denial of service. Enterprises using RuoYi in critical infrastructure, financial services, or government sectors could face operational disruptions and reputational damage. The vulnerability's remote exploitability without authentication increases the risk of widespread attacks if left unmitigated. Confidentiality may be compromised through data exfiltration, integrity undermined by unauthorized code execution, and availability affected by potential service interruptions. The medium severity rating reflects a balance between the ease of exploitation and the limited impact scope, but targeted attacks could escalate consequences. European organizations with limited patch management capabilities or exposed network segments hosting vulnerable RuoYi instances are particularly at risk.

1. Monitor y_project's official channels for patches addressing CVE-2025-14856 and apply them promptly once released. 2. Implement strict input validation and sanitization on the /monitor/cache/getnames endpoint to block malicious argument fragments. 3. Restrict network access to the vulnerable endpoint using firewalls or web application firewalls (WAFs) to limit exposure to trusted internal IPs only. 4. Conduct thorough code reviews and penetration testing focused on injection vulnerabilities within RuoYi deployments. 5. Employ runtime application self-protection (RASP) tools to detect and block anomalous code execution attempts. 6. Maintain up-to-date backups and incident response plans to quickly recover from potential exploitation. 7. Monitor logs and network traffic for unusual activity related to the vulnerable endpoint to detect early exploitation attempts. 8. Educate development and operations teams on secure coding practices and the importance of timely patching for third-party frameworks.
