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.
Avoid using LookupSubjects for negative authorization decisions and/or avoid using the broken schema.
