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.

kkFileView v5.0.0 through v5.0.2 contains a directory traversal vulnerability in FileController.java. The fileUpload, createFolder and existsFile endpoints accept a "path" parameter that is concatenated into the upload base path without validation, allowing unauthenticated attackers to create arbitrary directories and write arbitrary files outside the intended fileDir root via a crafted multipart request
