Security Advisory 0185

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.

A missing input validation vulnerability in the Fileserver upload API allows an authenticated attacker with file upload privileges to execute stored cross-site scripting (XSS). Successful exploitation could enable the attacker to hijack another CloudVision user's web session, potentially granting full access to their account and administrative permissions.
