The product does not handle or incorrectly handles an exceptional condition. As an impact it is known to affect integrity. The summary by CVE is:

SpiceDB is a graph database purpose-built for storing and evaluating access control data. Use of a relation of the form: `relation folder: folder | folder#parent` with an arrow such as `folder->view` can cause LookupSubjects to only return the subjects found under subjects for either `folder` or `folder#parent`. This bug only manifests if the same subject type is used multiple types in a relation, relationships exist for both subject types and an arrow is used over the relation. Any user making a negative authorization decision based on the results of a LookupSubjects request with version before v1.30.1 is affected. Version 1.30.1 contains a patch for the issue. As a workaround, avoid using LookupSubjects for negative authorization decisions and/or avoid using the broken schema.
