### Impact
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.
### Workarounds
Avoid using `LookupResources` for negative authorization decisions if using `1.22.0`.
### Patches
The only affected release is [v1.22.0](https://github.com/authzed/spicedb/releases/tag/v1.22.0), and it is patched in [v1.22.2](https://github.com/authzed/spicedb/releases/tag/v1.22.2) (there is no v1.22.1 release, though there is a git tag).
