- 7.5HighJul 30, 2026Tigera calico Path traversal / file handlingCVE-2026-6540Calico's Application Layer Policy (disabled by default), which enforces HTTP rules through Dikastes, fails to perform URL path normalization. As a result, HTTP requests using path-traversal segments, encoded slashes, or repeated slashes are not correctly evaluated by Prefix path rules. Dikastes authorizes the request under the permitted prefix while the downstream workload or a fronting proxy normalizes the path and serves the restricted endpoint. An attacker with network access and no special R
- 6.5MediumJul 30, 2026Tigera calico Auth bypass / access controlCVE-2026-41187Calico's apiserver wraps tier-scoped resources so that every operation runs through AuthorizeTierOperation, but the Delete override on NetworkPolicy, GlobalNetworkPolicy, and their staged variants is not invoked for DeleteCollection requests. A user holding the deletecollection verb or wildcard verbs on tier-scoped policy resources can bulk-delete policies in tiers they otherwise have no rights on, breaking the tier authorization boundary.
- 7.5HighJul 30, 2026Tigera calico Information disclosureCVE-2026-41186When Calico's shared debug server is enabled (disabled by default), the Calico kube-controllers and Goldmane components bind their Go pprof debug listener to 0.0.0.0 without authentication. Any pod with network reachability to the listener can retrieve the process heap, goroutine stacks (including function arguments), and command-line arguments. Depending on the process's in-memory state, the heap may contain sensitive material. The debug listener is opt-in but is unsafe when enabled because it
- 6.5MediumMay 28, 2026Tigera calico Information disclosureCVE-2026-41185When Calico is configured with the Azure IPAM plugin, the Calico CNI binary mutates the incoming CNI configuration to attach subnet information before delegating to the IPAM plugin. After mutating, the Azure IPAM helper logs the entire unmarshaled configuration map (stdinData) at INFO level to /var/log/calico/cni/cni.log on every CNI ADD and DEL invocation — once per pod scheduled or terminated on the node. When the cluster is deployed using token-based Kubernetes authentication, this log entry
- 6.5MediumMay 28, 2026Tigera calico Information disclosureCVE-2026-41184In Calico, the install-cni init container logs the rendered CNI configuration to standard output. When the configuration template uses the __SERVICEACCOUNT_TOKEN__ placeholder (Canal/Flannel-Calico deployments), the installer substitutes the live Kubernetes ServiceAccount bearer token before logging, exposing the token to any authenticated user with pods/log permission in the namespace with calico-node. The token holds patch privileges on pods/status, enabling annotation-based attacks against cl
