CVE-2025-24977: Citeum Opencti

Critical severity, CVSS 9.1. EPSS: 0.8% chance of exploitation in the next 30 days.

OpenCTI is an open cyber threat intelligence (CTI) platform. Prior to version 6.4.11 any user with the capability `manage customizations` can execute commands on the underlying infrastructure where OpenCTI is hosted and can access internal server side secrets by misusing the web-hooks. Since the malicious user gets a root shell inside a container this opens up the the infrastructure environment for further attacks and exposures. Version 6.4.11 fixes the issue.

Affected products

• Citeum Opencti: from 6.4.8, before 6.4.11 (fixed in 6.4.11)
