CVE-2025-13595 is a critical security vulnerability identified in the CIBELES AI plugin for WordPress, specifically in the 'actualizador_git.php' file present in all versions up to 1.10.8. The vulnerability is classified under CWE-434, which involves unrestricted file upload of dangerous types. The root cause is the absence of a capability check that would normally restrict who can invoke the update functionality. This flaw allows unauthenticated attackers to remotely trigger the download of arbitrary GitHub repositories and overwrite existing plugin files on the server hosting the WordPress site. By overwriting plugin files, attackers can inject malicious code, potentially leading to remote code execution (RCE). The vulnerability is exploitable over the network without any authentication or user interaction, making it highly accessible to attackers. The CVSS v3.1 base score of 9.8 reflects the critical nature of this flaw, with high impact on confidentiality, integrity, and availability. While no public exploits have been reported yet, the ease of exploitation and the severity of impact make this a high-priority issue. The vulnerability affects all versions of the plugin up to 1.10.8, and no official patches or updates have been linked yet, indicating that users must take immediate protective actions. The attack vector involves leveraging the plugin's update mechanism to replace legitimate plugin files with malicious ones, which can then execute arbitrary commands on the server, potentially leading to full site compromise, data theft, or defacement.

For European organizations, this vulnerability poses a significant threat to WordPress-based websites that utilize the CIBELES AI plugin. Successful exploitation can lead to complete server compromise, allowing attackers to execute arbitrary code, steal sensitive data, deface websites, or use the compromised server as a pivot point for further attacks within the network. This can result in severe reputational damage, regulatory penalties under GDPR due to data breaches, and operational disruptions. Public-facing websites of government agencies, financial institutions, healthcare providers, and e-commerce platforms in Europe are particularly at risk due to their high visibility and the sensitive nature of their data. The lack of authentication and user interaction requirements means attackers can automate exploitation at scale, increasing the likelihood of widespread attacks. Additionally, the ability to overwrite plugin files can facilitate persistent backdoors, making detection and remediation more challenging. The critical severity and network accessibility make this vulnerability a top priority for incident response and patch management teams in European organizations.

Given the absence of an official patch at the time of disclosure, European organizations should implement immediate compensating controls. First, restrict access to the 'actualizador_git.php' file by implementing web application firewall (WAF) rules that block unauthenticated requests to this endpoint. Use IP whitelisting or authentication mechanisms to limit who can invoke plugin update functionality. Monitor web server logs for suspicious requests targeting this script and unusual file modifications within the plugin directory. Employ file integrity monitoring to detect unauthorized changes to plugin files. Disable or remove the CIBELES AI plugin if it is not essential to reduce the attack surface. Ensure that WordPress core, themes, and other plugins are up to date to minimize additional vulnerabilities. Network segmentation can limit the impact of a compromised web server. Finally, prepare for rapid patch deployment once an official fix is released by the vendor. Conduct regular backups of website data and plugin files to enable quick restoration in case of compromise.
