Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Podman's kube play command (Go package github.com/containers/podman/v5 before 5.6.1, and github.com/containers/podman/v4 at 4.9.5 and earlier) can overwrite host files when a ConfigMap or Secret volume mount already contains a symlink to a host file. An attacker who can run a malicious container must first create the symlink on the volume, after which repeated runs of kube play write the user-supplied contents to the host location. Upgrade v5 to 5.6.1; no fixed version is listed for v4.
