Summary
SpiceDB, a Google Zanzibar-inspired database system, has an issue with negative authorization decisions using the `LookupResources` request in version 1.22.0. Users may incorrectly gain access to resources that should be blocked.
Risk Assessment
The organization may be exposed to unauthorized access to resources, potentially leading to serious security breaches. Specifically, improper authorization decisions could threaten data integrity.
Recommendation
It is recommended to upgrade to version 1.22.2 to mitigate this vulnerability. Users unable to upgrade should avoid using `LookupResources` for negative authorization decisions.
Other vulnerabilities in SpiceDB
See all- CVE-2026-55866Low
SpiceDB from 1.34.0 until 1.54.0 can return PERMISSIONSHIP_HAS_PERMISSION instead of PERMISSIONSHIP_CONDITIONAL_PERMISSION or PERMISSIONSHIP_NO_PERMISSION because checkRequestToKey() and checkRequestToKeyWithCanonical() in internal/dispatch/keys/computed.go omit CheckHints when constructing dispatch Check cache keys. A result computed for one hint set can poison the cache entry used by a semantically different authorization check.
- CVE-2026-46668Low
In SpiceDB from version 1.15.0 to before 1.52.0, caveat structures with nested lists can result in improper cache reuse. This issue has been patched in version 1.52.0.
- CVE-2025-65111Medium
SpiceDB is an open source database system for creating and managing security-critical application permissions. Prior to version 1.47.1, if a schema includes the following characteristics: permission defined in terms of a union (+) and that union references the same relation on both sides (but one side arrows to a different permission). Then SpiceDB may have missing LookupResources results when checking the permission. This only affects LookupResources; other APIs calculate permissionship correctly. The issue is fixed in version 1.47.1.
Original NVD description (English source)
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.
