Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Github.com/openfga/openfga, 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

# Overview Some end users of OpenFGA v1.5.0 or later are vulnerable to authorization bypass when calling Check or ListObjects APIs. # Am I Affected? You are very likely affected if your model involves exclusion (e.g. `a but not b`) or intersection (e.g. `a and b`) and you have any cyclical relationships. If you are using these, please update as soon as possible. # Fix Update to v1.5.3 # Backward Compatibility This update is backward compatible.
