CVE-2025-13428 is a vulnerability classified under CWE-20 (Improper Input Validation) affecting Google Cloud SecOps SOAR, a security orchestration, automation, and response platform. The vulnerability specifically targets the custom integrations feature, where an authenticated user assigned the IDE role can upload Python packages to the server. Due to insufficient validation of the uploaded package contents, an attacker can include a malicious setup.py script that executes arbitrary code during the package installation process on the server. This leads to remote code execution (RCE), allowing the attacker to potentially take full control of the SecOps SOAR server environment. The vulnerability does not require user interaction beyond the authenticated upload, and no additional privileges beyond the IDE role are necessary. The CVSS 4.0 score is 8.6 (high), reflecting the network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. Google has addressed the issue by automatically upgrading all customers to version 6.3.64 or later, which includes proper validation and sanitization of uploaded Python packages to prevent execution of malicious code. There are no known exploits in the wild at this time, but the potential impact is significant given the critical role of SecOps SOAR in security operations.

For European organizations, the vulnerability poses a serious risk as it enables remote code execution on a critical security orchestration platform, potentially compromising the entire security operations infrastructure. This could lead to unauthorized access to sensitive security data, manipulation or disruption of automated incident response workflows, and broader network compromise if attackers pivot from the SOAR server. The confidentiality of incident data and integrity of automated responses could be severely undermined, impacting regulatory compliance and operational resilience. Availability of security operations could also be disrupted, delaying detection and response to other threats. Organizations relying heavily on Google Cloud SecOps SOAR for centralized security management, especially in sectors like finance, energy, and government, face heightened risk. The automatic patching by Google reduces immediate risk, but organizations must verify their environment and remain vigilant for any signs of compromise or attempted exploitation.

Beyond ensuring that all Google Cloud SecOps SOAR instances are running version 6.3.64 or later, European organizations should implement strict role-based access controls to limit IDE role assignments only to trusted personnel. Regular audits of user roles and permissions can prevent unauthorized users from uploading potentially malicious packages. Monitoring and logging of package uploads and installation activities should be enhanced to detect anomalous behavior indicative of exploitation attempts. Network segmentation of the SOAR server can limit lateral movement if compromise occurs. Additionally, organizations should integrate runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions to detect suspicious execution of scripts like setup.py. Conducting internal penetration tests and red team exercises simulating this attack vector can validate defenses. Finally, maintain up-to-date backups and incident response plans tailored for SOAR platform compromises to enable rapid recovery.
