A vulnerability was found in Envoy, where using SDS with Combined Validation Context Using the same secret (e.g. trusted CA) across many resources together with the combined validation context could lead to the “static” part of the validation context to be not applied, even though it was visible in the active config dump.
A vulnerability was found in Envoy version 1.13.0 or earlier may consume excessive amounts of memory when proxying HTTP/1.1 requests or responses with many small (i.e. 1 byte) chunks.

CNCF K3s 1.32 before 1.32.4-rc1+k3s1 has a Kubernetes kubelet configuration change with the unintended consequence that, in some situations, ReadOnlyPort is set to 10255. For example, the default behavior of a K3s online installation might allow unauthenticated access to this port, exposing credentials.

An issue was discovered in Cloud Native Computing Foundation (CNCF) Helm through 3.13.3. It displays values of secrets when the --dry-run flag is used. This is a security concern in some use cases, such as a --dry-run call by a CI/CD tool. NOTE: the vendor's position is that this behavior was introduced intentionally, and cannot be removed without breaking backwards compatibility (some users may be relying on these values).
