Descripción
*** Pendiente de traducción *** On a Kong Mesh global control plane, resources received over the zone-to-global KDS sync are attributed using the in-band, sender-controlled ControlPlane.Identifier rather than the authenticated zone identity derived from the connection. Authenticated zones can have the global control plane store and re-distribute those resources as belonging to another zone.<br />
<br />
<br />
<br />
The result is a cross-zone isolation bypass: the holder of a single enrolled zone&#39;s credential can inject, attribute, and overwrite resources in another zone&#39;s namespace mesh-wide.<br />
<br />
<br />
<br />
<br />
The root cause lives in Kuma&#39;s open-source KDS sync code, which Kong Mesh&#39;s control plane is built on.
