CVE-2022-36454Network attack vector

Authenticated name impersonation via unauthorized profile changes

Published Oct 25, 2022 · Updated May 7, 2025

Improper authorization in Mitel MiCollab 9.5.0.101 and earlier allows remote authenticated users to impersonate another user's name. The MiCollab Client API applies profile-parameter changes without properly authorizing the requested name value. A valid account is required, and the documented consequence is name impersonation rather than account takeover or service interruption.
