Insufficient Authorization and User Boundary Validation in Omada Controller MSP

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

In Omada Controller MSP mode, the user-confirmation endpoint fails to enforce the required permission check. An authenticated user can supply a caller-controlled Identifier parameter to validate credentials for another account and receive responses that distinguish nonexistent users, invalid passwords, and successful authentication.  Successful exploitation may allow user enumeration, credential verification, and unauthorized access to MSP resources or compromise of targeted accounts.
