CVE-2021-27402
The SAS Admin portal of Mitel MiCollab before 9.2 FP2 could allow an unauthenticated attacker to access (view and modify) user data by injecting arbitrary directory paths due to improper URL validation, aka Directory Traversal.
Does this matter?
Lower severity and a low EPSS score (1.07%). Track it; it rarely justifies an emergency change on its own.
