Summary
SpiceDB's LookupResources may return partial results
Details

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 used 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, and it is patched in v1.22.2 (there is no v1.22.1 release, though there is a git tag).
