CVE-2026-6720 HIGH PATCH This Week

Credential disclosure in Tigera Calico's calicoctl CLI exposes cluster-access secrets through verbose logging output. When operators run calicoctl with --log-level=info or --log-level=debug, the tool serializes its entire connection-configuration struct (including bearer tokens, etcd passwords, and inline PEM client certificates/keys) to stderr in a single log line, making them harvestable by anyone with access to CI logs, terminal recordings, or support transcripts. The issue is patched upstream but no public exploit is identified at time of analysis; default panic-level logging means standard deployments are not exposed.
