Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Omni versions 1.3.0 up to 1.6.6 and 1.7.0 up to 1.7.3 let an authenticated user with the Reader role read the ImportedClusterSecrets resource, which holds the CA private keys of imported Talos clusters whose secrets were never rotated. An attacker who obtains these keys and can reach the cluster's Talos or Kubernetes APIs over the network can gain full control of that cluster. Upgrade the github.com/siderolabs/omni package to 1.6.6 or 1.7.3, or rotate the secrets of imported clusters.
