Business impact
Successful exploitation of CVE-2023-3277, a critical vulnerability (CVSS 9.8) affecting mstore api, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
