Description · from the CVE record

OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, a Kubernetes REST endpoint exposes two methods that deserialize untrusted data from the request body. These endpoints do not enforce any authentication or authorization checks. This issue may lead to pre-auth RCE. This issue was fixed in 4.0.3 by not using deserialization at KubernetesResource side.
