The Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities:
Two remote code execution vulnerabilities. An attacker can exploit these to bypass authentication and execute unauthorized arbitrary commands. (CVE-2022-22003, CVE-2022-22004)
An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2022-23252)
