The record
K3s is a fully conformant production-ready Kubernetes distribution. Prior to 1.35.3+k3s1, 1.34.6+k3s1, v1.33.10+k3s1, a path traversal vulnerability exists in K3s's etcd snapshot decompression functionality. Zip files containing archive members with maliciously crafted names can be written to arbitrary locations on the filesystem when an administrator restores the archive as a compressed etcd snapshot. This vulnerability is fixed in 1.35.3+k3s1, 1.34.6+k3s1, v1.33.10+k3s1.
