SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions. Any user making a negative authorization decision based on the results of a `LookupResources` request with 1.22.0 is affected. For example, using `LookupResources` to find a list of resources to allow access to be okay: some subjects that should have access to a resource may not. But if using `LookupResources` to find a list of banned resources instead, then some users that shouldn't have access may. Generally, `LookupResources` is not and should not be to gate access in this way - that's what the `Check` API is for. Additionally, version 1.22.0 has included a warning about this bug since its initial release. Users are advised to upgrade to version 1.22.2. Users unable to upgrade should avoid using `LookupResources` for negative authorization decisions.
The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.
