GHSA-j85q-46hg-36p2: SpiceDB: LookupSubjects may return partial results if a specific kind of relation is used
Background
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.
Impact
Any user making a negative authorization decision based on the results of a LookupSubjects request with version before v1.30.1 is affected.
Workarounds
Avoid using LookupSubjects for negative authorization decisions and/or avoid using the broken schema.
