"The Microsoft Office Products are missing security updates. They are, therefore, affected by multiple vulnerabilities:

  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.

  - A security feature bypass vulnerability exists. An attacker can exploit this and bypass the security
    feature and perform unauthorized actions compromising the integrity of the system/application.
    (CVE-2025-29816)

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute
    unauthorized arbitrary commands. (CVE-2025-26642, CVE-2025-27745, CVE-2025-27746, CVE-2025-27748,
