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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
