Any SpiceDB cluster with any schema where a resource being checked has more than 65535 relationships for the same resource and subject type is affected by this problem.

The issue may also lead to a panic rendering the server unavailable

The following API methods are affected:

Impact

Permission checks that are expected to be allowed are instead denied, and lookup subjects will return fewer subjects than expected.

Workarounds

There is no workaround other than making sure that the SpiceDB cluster does not have very wide relations, with the maximum value being the maximum value of an 16-bit unsigned integer
