Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-755: Improper Handling of Exceptional Conditions, where the product does not handle or incorrectly handles an exceptional condition. In SpiceDB, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
