CVE-2025-46439 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Vladimir Prelovac Plugin Central software, affecting versions up to 2.5.1. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged request to a web application in which they are currently authenticated, potentially causing unauthorized actions. In this case, the CSRF vulnerability enables a path traversal attack vector, which could allow an attacker to manipulate file paths and access or modify files outside the intended directory scope. This combination of CSRF and path traversal is particularly concerning because it leverages the victim's authenticated session to perform unauthorized file system operations, potentially leading to information disclosure, unauthorized file modification, or other malicious activities. The vulnerability does not require user interaction beyond the victim visiting a maliciously crafted webpage or clicking a link, and no known exploits are currently reported in the wild. The absence of a patch at the time of reporting increases the risk window. The vulnerability is classified under CWE-352, which highlights the risk of unauthorized state-changing requests due to insufficient request validation mechanisms such as missing anti-CSRF tokens or improper session handling. Given the nature of Plugin Central as a plugin management tool, exploitation could impact the integrity and availability of plugins or the host system's file structure.

For European organizations, the exploitation of this vulnerability could lead to unauthorized changes in plugin configurations or unauthorized access to sensitive files on systems using Vladimir Prelovac Plugin Central. This may result in data leakage, service disruption, or the introduction of malicious code through compromised plugins. Organizations relying on this plugin for website or application management could face integrity breaches, potentially undermining trust and compliance with data protection regulations such as GDPR. The path traversal aspect increases the risk of exposing sensitive configuration files or credentials stored on the server. Additionally, if exploited in environments with high privileges, attackers could escalate their access, leading to broader system compromise. The medium severity rating suggests a moderate risk, but the combined CSRF and path traversal vectors could have significant consequences if leveraged in targeted attacks, especially in sectors with critical infrastructure or sensitive data processing.

1. Implement anti-CSRF tokens in all state-changing requests within Plugin Central to ensure that requests originate from legitimate users. 2. Enforce strict validation and sanitization of all file path inputs to prevent path traversal, including normalization of file paths and restricting access to allowed directories only. 3. Apply the principle of least privilege to the Plugin Central service account, limiting file system permissions to only necessary directories. 4. Monitor web server and application logs for unusual or unauthorized requests indicative of CSRF or path traversal attempts. 5. Educate users about the risks of clicking on untrusted links while authenticated to critical systems. 6. Since no patch is currently available, consider temporary compensating controls such as web application firewalls (WAFs) with rules to detect and block suspicious path traversal patterns and CSRF attempts. 7. Regularly review and update plugin and system configurations to minimize exposure. 8. Engage with the vendor or community to track patch releases and apply updates promptly once available.
